Dumping friends over politics or religion

[Mister Agenda]

I've always felt that you owe a real friend who hasn't deliberately hurt you beyond reason (knowingly slept with your S.O., stole your wallet, planted weed on you, shit like that) a chance to talk it out and lay on the line what's bugging you before you walk, give them a chance to make whatever case they might have. After hearing you, it might be them that decides to walk. This only applies to real friends, though; you can't owe a heart-to-heart to everyone you don't actively dislike.
