BEFORE YOU READ MY POST: Don't assume that because I'm being general, that I mean ALL Christians feel the same way...I'm going by personal experience.
I have major issues with the way Christianity says to handle the situation.
Many Christian churches (including the one I attend...yeah I go to church. I use it as an educational model

) teach that you should try to spread the word as much as you can. But they teach also that if someone refuses the word of God, then they are bad and that you shouldn't even associate yourself with them. The church I've attended even says that you shouldn't marry someone who doesn't share your faith.
Yet Christianity also claims to teach love and compassion for everyone...hating the sin and not the sinner. That makes no sense to me. It's a complete contradiction of the same teaching as above. In one case they're saying "if you believe in OUR God, then we love you. Otherwise, get out." And in the other they're saying "we love you but not your beliefs."
That bothers me because it's basically forcing your religion with the promise of the acceptance of your peers. It's simple peer pressure. People are autonomous for a reason. Let people practice the free will they're given. If that means they want to reject your religion in favor of their own, then so be it.
