Your manifesto contains way too many words for me.
My "atheist manifesto" is very easy; I just don't believe in the existence of a god or gods.
That's it.
I'll explain it like this: I prefer to have a look at the empirical, verifiable evidence for what somebody tells me before I accept it. If I am not educated enough on a subject to be able to even have a meaningful opinion, I also look at the consensus of the specialists on it and the method of theirs obtaining their decision.
But, then again, I don't normally conform to the group mentality. Groups are known to reach very disturbing conclusions just to feel "in". Group pressure is a very strong pressure. (Creationists would call it a " scientific law"
).
Objective and verifiable, empirical evidence for a phenomenon normally does it for me.
