What aviel said. Literally nobody here supports either Nazi or Antifa violence. Also what Crimson said: we're all pointing at the other side and saying "No, you have more extremists! Your extremists are worse!"
I suspect that much of the problem is also that, given the shitty political atmosphere right now, virtually all of us are coming into this forum with a hell of a lot of baggage from political disagreements with facebook or IRL friends. Noodles and Kate are very right: many conservatives have lost friends due to liberals overreacting and unfairly conflating them with the worst people on the right. On the other hand, many of us on the left have also had problems with conservative friends and family members (it's been difficult for me to watch some family members polarize into unabashed white supremacists when before it was merely "don't get into Thanksgiving dinner political conversations, mkay?")
This hurts everybody and it sucks.
