there was a roseanne christmas-time episode once that had this really great line.
the setup: roseanne and her mom were constantly bickering over roseanne's childhood and how ideas like jesus were forced upon her. her mom was defeding the notion of christianity and how it helped raise her, so she used it for her kids. the argument was increasing and getting more and more intense, both were at each others throats, when, suddenly, roseanne's sister jackie jumps between the two --
"stop it, stop it! for one night, no more religion talk -- its christmas!"
heh 
well, llance, i can't completely relate with your scenario, as im just a youngin'. i have been the kid in a situation VERY similar to yours, tho, so i do see your point.
however, much like the wise sage "jackie" mentioned above... sometimes, to me, it just seems like its more the idea of the holiday and man's good will, rather than relating to god or religion at all.
am i a dumbass for wanting proof? probably. i know im not the only one, but i've heard the arguments before. if god really IS there, why the hell would he prove himself to me? he'd have to do it for EVERYone. it'd probably just get annoying for him.
bottom line, i aint got no frickin clue. i'd never shit on anyone for their religion and/or religious choices, cuz thats not cool at all. and, like my childhood christmas' faith, and the happiness it brought me, id NEVER wanna be sucha dick that i'd go and ruin that for someone else, even if it were possible that i "knew" the answer was opposite to their beliefs.
