Can atheists convert theists?

[Oldandeasilyconfused]

The purpose of this thread is to establish how an atheist would convert a theist to atheism.

First, it's de-convert,as atheism is not a belief system,but merely the absence of belief.

I guess your question is more "how would an atheist cause a believer to lose faith?"

I think that would depend on the believer. Faith is not built on reason,but is the antithesis of reason,IE beleif without evidence. Reason cannot easily be used to dissuade someone from a position in which reason had no part in forming. I think that's why relatively few believers ever seem to stop believing completely. As Augustine Of Hippo said "give me the child and I care not who has the man"

My answer to your questsion is "I don't know". It's not a question to which I've ever given any thought. That's because I really don't care about the personal beliefs of others [unless they get in my face] and because I despise proselytising .
