How do you figure out that "most white people are christian?" Most white people are atheists, non-believers or couldn't give a f***ers.
Most white people don't give a monkeys, in my experience. They have other, more pressing things to worry about then a spirit in the sky (oh great, now I'll be Tourrettes'ing that all day) and handing over their hard earned to one of the richest institutions in the land on the promise that a mythical ghost from an alien religion will save them.
If people don't have the sense to see that the whole thing is bullshit, why do we want to save them? You can argue a christian into a corner with facts and figures and prove to them that christianity isn't theirs and they still won't see the light.
Above post is my opinion unless it's a quote.
