I'll definitely be seeing Religulous, but I'm of the same opinion as Bill Maher (sp?). I think that religion, if it brings you peace or hope or whatever, is generally a good thing. However, if people place too much stock in it, if they use religion as a structure on which to base their lives, then religion does nothing but breed passivity and discourage free thought.
Religion can be a good thing as long as you don't see it as unquestionable truth. Letting three thousand year old people do all of your thinking for you is just plain asinine
