Neighbor turning against neighbor. People who have known each other for years, whose children have played together, suddenly divided by rising cycles of suspicion, hate, and violence. One of the most chilling aspects of the Holocaust, and of other genocides, is the recurrence of this dismal phenomenon in virtually every culture in which genocides have taken place.

Not everyone on the left is the enemy. They are just dumb. "Never attribute to malice what you can attribute to stupidity".
Just try to remember everyone is human. We are legit on the path to genocide and war. Following the playbook exactly.
Talk to Serbs and Croats about that. They have quite recent experience.
