I have not reduced a human life to a parasite. What I have said could properly be stated such as this though: Whether it is human is of no consequence to whether a host should be able to, morally and legally, kill a parasite. I pretty much ignore if it is human if it exists as a parasite and can't survive in any other way, it is irrelevant to me.
That is sufficient and the problem. It is never negligible whether the individual is human or not. In fact no other factor carries more weight that I can think of. This is getting depressing.
Let me add an exception.
It is never negligible whether it is a human life if it ever was. Without God humanity has no special significance. We are just another genetic anomalies with no more inherent value that any other bag of atoms.
You made the argument that the rule justifies ignoring even the potential of exceptions. If you do not know what that is evidence of the problem.
I do not need objective moral foundations for anything at all. Actually, I don't even think such a thing exists.
So whether a moral duty or value actually exists in fact is irrelevant to you. You might need an attorney. Since the irrational ship has left the harbor what excuse have you even invented to justify out killing off more humans that all religions combined without even the potential of actually being right, or even an actual right even existing.
Why not ? Why make it an exception ?
Again since rationality and even a potential fact of the matter is no longer even a goal let me use an atheistic argument I constantly here. I suggest that without God that all morality is merely preference. I get in response "We can look at evolution (which is a theory and not an entity to begin with) and clearly see survival he goal and pattern laws on that. So even without the desire to be objectively moral how can you even claim to be consistent with materialism or naturalism. What exactly beyond your preference are you consistent with.
It is not my burden. You made a claim to knowledge. You said since every X then Y. So why is that.
It is not. Let me teach you basic biology: A carnivore is not a parasite for feeding on meat from other animals.
Oh crap, the most boring subject in history.
So a lion eating it's own young is just fine, but a baby through no fault of it's own attached by an umbilical can be killed for any reason?
Can you find me in any law, in any society, from any time, that is patterned on the idea that killing unborn humans is ok because other parasites have no rights to life. I had to write this 4 times because I cannot not even make that idea coherent.
I not only have no idea how you get there from anywhere I am becoming pretty sure I don't even want to know.
