My point: The conversation topic does nothing.
Theist make a claim, atheist disagree with theist, they debate who is right, i cannot see how the conversation topic "does nothing".
The claim/statement alone (talking about the claim not the person making it) "God exists" does nothing.
I cannot see why you need to separate "the claim making by some theist" from "the theist who making the claim".
Some theist claims that "God exists" and non-believer should obey their God, atheist disagree with the claims, that's why they debate.
Atheist is debate with "the theist who making the claim".
Atheist is
not debate with nobody but a "claim" that imagined by the atheist himself.
Without "the theist who making the claim", there'll be no "claim" to begin with.
That claim does not hurt anyone. It is an empty or illogical statement creating a title an attributes for non existent/space/nothing. This is illogical.
I cannot see your reason for the needs to want to separate "the claim" from "the theist who making the claim".
Atheist disagree with "the claim which making by some theist", they express their opinion why they think so.
I cannot see why it is illogical.
The theists who have this illogical claim are the ones (some) opposing the threat. "They" (not the belief) are using their illogical claim against people. (E.x. the Church). Hence, why it Is logical for atheist to talk "about" it. That does not erase that the claim in itself is illogical.
In your OP you say that "the debate begin from atheist" is illogical to begin with, now you say that "the claim which claims by some theist that they believe their God exist" is illogical, which one do you think is illogical?
As an athiest to external deities, I debate this illogical claim because I want to understand how it does make sense to the theist. What are the methods and experences do they have that Id understand how they make this illogical statememt true. "For me" it has nothing to do with how the faith affects people. It does nothing "on its own." People use their faith for or against people.
As a former believer, I read scripture and it did not affect me negatively. It did nothing. Its a book saying something that is not true.
It was the people who used this book and Church teachings that influenced me. They said I should believe in God. Rather than address their belief (which Gods existence claim means nothing, why should I argue it), I address their actions on me to belief this claim. I ask about how the Church views this claim. How they make sense of it. To debate the existence of God does not make sense "For Me" becausenit acheives nothing on those who are enforcing their belief.
Other atheist is debate with "the theist who making the claim".
Other atheist is
not debate with nobody but a "claim" that imagined by the atheist himself.
Other atheist disagree with the claim, that's why they express their opinion why they think so, i cannot see how it is illogical for them to do so.
Insteadn of my just learning why God exists (for my benefit since He does not), Id think more of how this belief affects peoples actions. I have seen peoples lives saved by their beliefs. I have listened to businesses being shut down because of people (not the belief) impose their belief on the manager to where she had to shut it down temporarly.
"this belief affects some believer's actions", and then "some believer's actions affects other non-believer", then non-believer express their opinion that why they disagree with "the believer's action which affects them".
I cannot get your point why atheist is illogical to express their opinion.
Every year I see people go into the Church. It is beautiful when they live how their belief teaches them. Sometimes they do not follow it (hence sin). To help them through it, it is logical to talk about their belief.
You're right.
If there is no problem, because the claim is illogical, the best I can do as an atheist is to learn from it.
For you there is no problem.
But for other atheist there is problem.
Other atheist disagree with the claim which making by some theist which the claim may cause this theist's action to affects the atheist's life.
This is why atheist debate with theist.
I cannot see your point lead to the conclusion that atheist is illogical to debate with theist about the topic of God's existence. Your point doesn't make sense to me.
