Hmmm disagree. If someone's politics are violence, and they have a serious path to enacting them, it's self defense. Self defense is generally acceptable.
I don't want to politely walk into a concentration camp because a bunch of people in states I don't even live in voted to exterminate the queers and their friends.
Also anyone who's going to say "Gay marriage is violence against society" is an asshole and wrong. Anyone who says abortion is murder but isn't doing jack fuck to help living humans is not worth listening to. Just to preempt the "well they think the same about you!" nonsense.
