I'm Presbyterian. I'm a member of the church, and I've been very involved in the past(not so much now, due to the conservative nature of my current congregation.) I've found that those who believe need no proof, and those who don't simply don't get it. I never ever force my faith on other people. I've never forced in any of my exes, but I also will debate you when people start tearing into my faith, or me for having it. Faith is hope. It gives us something more to strive for, to believe in. That's why there are so many religions and denominations. It speaks to human nature to aspire, to want more, and our longing for... well... longevity, and eternity.
I find that someone who wouldn't want me, ALL of me, and my thoughts, probably doesn't deserve me in the first place, and wouldn't appreciate me if they had me. They'd simply spend their time "corrupting" or trying to alter me, which isn't healthy for either party involved.... and militant atheism is just as bad as militant religion. Athiesm isn't to be forced on people, you can't do it. It's reason, "enlightenment," and as such should be talked about and never forcefully....(I seem to recall an athiest saying that once....)
