I know there were "technical" reasons for not condemning the calls for genocide, like it was not a specific enough of a threat or whatever they argue. But let's say it's "wrong," Then what are you going to do about all the people of all colors who call for the genocide of whites, one way or another? No one can say this isn't allowed at these schools. I'm sure there are tons of professors there who do that constantly, who have written whole books on the topic of how to abolish whites as a category. This should rub whites the wrong way but it largely doesn't. Israelis say Palestinians are ALL terrorists and should be disappeared and they are doing it and it's fine. They say Palestinians would outbreed them in a one state solution and this would constitute a soft genocide of Jews. True or not, Jews don't allow this view for whites, "there is no replacement of whites going on at the behest of Jews, it's an antisemitic conspiracy theory" and in the next sentence they brag about what they are doing.
So it's not about whether genocide is right or wrong, it's WHO is being genocided that decides the wright or wrong. Jews don't interfere with black speech against whites, they are actually stoking it.
Regsrding UNZ, people wonder why he is allowed to go on publishing and hasn't been canceled by the ADL. Unz is constantly taunting them, trying to get them to go after him but the best they could do was labeling his site antisemitic in some small blurb. Jews are constantly weighing options on what to do, sometimes they think resistance might overall be a net negative for their cause so they low some things. Jews might support Nazis or Isis or Al Qaeda, as they are admittedly doing, it all hinges on the question of "is this good for the Jews?"
