I lost a great life long friend 4 years ago and we gamed together. Sometimes when religion came up in a game we discussed it. Disagreed about it. Picked the controllers back up and played some more.
I'm a Christian, the opposite happens as well. Why can't we discuss our beliefs in a civilized manner? I will never tell my "pastor" about an atheist or theist in my area. Especially considering I have atheist friends.
