Well, all I can say is let the mods do their job and decide who's trolling and who's actually trying to start a discussion.
Look at the forum title; "Debate Politics, Religion, and Philosophy". No one has to come here and debate (sometimes argue) about what they believe if they don't want to.
As far as atheists having to prove the big bang, or evolution or whatever, that's totally irrelevant. Mythology provides answers to questions about the origin of the universe and mankind. That doesn't mean it's the right answer, and it doesn't mean you have to provide your own answer in order to disbelieve their answer.
