There are several issues with your responses:
1. You prove my original claim is true that the PoE question only makes sense in the context of being raised as a logical objection to the idea of God as found in the Bible.
Plantinga’s book “God, Freedom, and Evil” was only inspired to be written as a response to atheist philosophers attacking the idea that the Biblical God could be logically consistent.
The PoE as a philosophically meaningful question simply doesn’t exist outside of being raised as an objection to the Biblical idea of God (The PoE as formulated by J. L. Mackie) – and virtually no religion today has this idea of God unless that religion can trace it’s roots back to Judaism.
2. It disproves your claim that the PoE can be a philosophically neutral question. As I have pointed out, you have no purely logical or philosophical grounds for asserting the attributes of the PoE (even your version of the PoE). Your question can only exist in opposition to what someone else already claims to believe. And virtually the only religions that you’re going to find with such beliefs are rooted in Judaism.
3. Saying you are posing this question to “theism” in general is not coherent for two reasons:
a) Because there is nothing inherent in the idea of a theistic being that forces you to believe in those premises.
b) Because theism in general can’t be said to have any commonly accepted set of beliefs. You are mistaken if you think it can because you’re looking at what Abrahamic religions believe and then concluding that one must believe only that to be a theist.
Plantinga is not merely giving a defense of “theism” in general – he’s giving a defense of Biblical theism specifically. Because the PoE formulate he was responding to was put forth by J. L. Mackie as an attack on the Biblical idea of God as supposedly being illogical.
The PoE is therefore not posed as a challenge to theism in general – it’s posed a challenge to Biblical theism specifically (or those that share those same Biblical beliefs).
4. You aren’t actually letting the other person define what their premises are and then using their premises against them. You are trying to impose your premises upon them by defining what omnibenevolence and omnipotence mean to you, even though you don’t accept them to even be real things, instead of going off what those terms mean to the other person who accepts them to be real things.
If you are trying to claim that your definition of the terms is consistent with what a particular person or religion believes then the burden is on you to first identify whose position you are attacking. And then the possibility exists to examine their position to see if you have accurately represented what they believe.
If you don’t identify whose position you are attacking then there’s no way of questioning whether or not you are right to start with the premises you have invented.
That is why, under those standards, you could get away with formulating an argument that proved god doesn’t exist from the premise that god hates ice cream and ice cream exists – because you don’t have to believe it or even find someone who does believe it.
Earlier you tried to say you were posing the question to whoever believed in those premises, even though you chose to define the premises according to your own ideas about what they should be.
The problem with that approach is it can’t be logically said to prove anything about any topic without identifying who actually believes what you claim.
I could argue from the premise that god hates ice cream to prove god doesn’t exist and then when challenged on what the relevance of my argument was I could simply reply “well, I’m just talking about anyone who does believe god hates ice cream. If they believe my premise then this applies to them. I know they are out there somewhere”.
But such an exercise is not philosophically or logically meaningful to helping us arrive at what is true. You only arrive closer to what is true by challenging what people actually believe.
5. You are misrepresenting what Biblical theists believe when you try to strip away many of the defining attributes of God that they hold as premises and then demand the Biblical theist accept your stripped down premise as their own.
Although you might be correct to say that most Biblical theists would agree with you that God doesn’t like people to suffer – your argument becomes fallacious on the basis of what you try to require them to omit from their beliefs.
You are trying to arbitrarily force out of the discussion by the way you reformulate your premises other Biblically derived presumptions about God that the Biblical theist would hold; demanding they accept your stripped down premises instead.
The following are Biblically derived presumptions you are trying to remove from the equation of what a Biblical theist actually believes (or at least what is required to be believe to be consistent with the Bible):
-Objective morality exists.
-God is the source of objective morality.
-Morality comes out of the nature of who God is.
-God is all good, morally speaking.
-God designed us to be like Him, but gave us the free will to choose.
-God is eternally existent with nothing before him.
-God is subject to nothing but himself. All things are subject to Him.
-God cannot lie or contradict his nature.
-Nothing gave God His nature. Everything else derives it’s nature from God.
Which goes back to why your analogies often fail to be correct is because they deny important premises about God’s nature which allow the Biblical theist to come to the conclusions they do (such as your mars attacks analogy ignoring God’s presumed omnibenevolence and omniscience)
Since you often refer to Plantinga: What formulation of the PoE was he responding to? It could not be the formulation you are proposing which denies objective morality.
J. L. Mackie formulated his PoE as an attack against the major monotheistic religions.
All the major monotheistic religions will assert that objective morality exists and that God is all good in an objectively moral sense.
Therefore, the PoE question posed to Plantinga must have assumed those two things existed otherwise it could not be a coherent objection against what they actually believe.
Any PoE question that didn’t assume objective morality existed would not be a question that were relevant to any religion that has Judaic roots.
And the PoE as a question is not relevant to any religion that doesn't have Judaic roots by virtue of the fact that basically only Judaic rooted religions believe in those combined attributes about God.
So, therefore, intrinsically, the PoE question must assume objective morality exists in order to be theologically or philosophically relevant. Because the only religions to which the question is relevant all assume objective morality exists and assume God is all morally good.
So what exactly is the source of the premises as you have defined them? Whose view are you challenging?
It can’t be theism in general as there is no shared definition of belief for what that means.
Plus it would be a contradiction since some concepts of theism outright contradict your premises.
Only the Abrahamic religions would even believe in the premises of the PoE.
So whose idea of God are you actually trying to challenge?
Is it Abrahamic shared conceptions of God in general?
Is it Christianity specifically?
Is it an individual like Plantinga’s beliefs specifically?
What you identify as the source of your PoE premise will determine how we approach it.
If you don’t identify a source for the premises then the implication is that you are the one providing your own premises to the question.
Which, in that case, brings us back to what I said about how the burden would then be on you then to give a reason for why you hold to those premises. But you can’t give a reason for most of them based on your worldview. You are 100% dependent on someone else providing the premises to you in order for you to attack them unless you believe you can argue in favor of a premise on the basis of philosophy/logic alone which they then must accept. But you don't even try to do that for most of the premises you bring into the question.
Coming full circle back to what I originally said: The PoE question is only meaningful and relevant as a challenge to the concept of God as found in the Bible. As you will probably not find such a concept of God believed by any religion that doesn’t have it’s roots in Judaism at some point.
Therefore, in light of this, any discussion about the PoE inherently must become not merely a philosophical question but a theological question about what the Bible says about God.
