Socialism: We are divided by class. The bourgeoisie oppress us and will never share their power, our only choice is revolution and eradication. (Communism will come after the revolution)
National Socialism (Nazis): We are divided by nation. The Jews oppress us and will never share their power, our only choice is revolution and eradication. (Add in Brits, French, Czech, Poles...)
Race Socialism: We are divided by race. The Whites oppress us and will never share their power, our only choice is revolution and eradication.
Sex Socialism: Surely you get the point by now.
I realize this is off topic, where do I put it?
After WW2 the slavic peoples of eastern europe were so angry at the nazis they ethnically cleansed many areas of germans who had been living there for centuries. They weren't egged on by jews (who had been mostly killed). The cycle of vengeance repeats until it is broken. That needs justice, and justice does not murder the innocent.
