Well, that's my point, it's an arrogant, condescending, attitude. Theists shouldn't be critised for being certain in the belief in God if atheists aren't. It's the same idea isn't it? I mean, thesists believe in God, so why critisise them for expressing that belief? Their freedom is an atheists freedom and vice versa.
Thanks for the welcom, and sorry to not make a distinction on the whole thing of some scientists believing in God and some not. I'll try to be more clear and specific next time.
I would agree that an atheist who is 100% no god/gods/etc. do not exist is a bit arrogant.
However, most atheists simply believe no gods exist, but they are open to the possibility they might be wrong (that's how I feel, and I'm still waiting for some evidence
)
