Ah... How they don't see that making race or ethnicity the center of everything makes them just like the people they hate is kind of amazing.

One can oppose jewish supremacists or white supremacists or black supremacists without hating all jews, or all whites, or all blacks. If you know (or even just know of) a single counter example (a libertarian jew/white/black/etc) then it should be obvious that damning the entire race would mean damning innocent people. Collective punishment is a war crime for a reason.
