Thanks for posting this. This was really interesting to watch.

Does she fear a US that's minority white?

I don't think she does. She implicitly knows as a Jew she will be safe when the US collapses. She will simply go to another country or go to some type of bunkered community. The irony! The Chutzpah on this Jew to criticize 'brahmin' entitlement when her own people are ten times worse at criticizing their hosts.

What's happening?

My gut tells me she's just playing a role. Jews are setting themselves up for the next configuration of controlled opposition (the neo con hustle is dead). I see Jews like Bill Maher and Bari Weis doing a very similar dance. Dissidents will probably not fall for this but the Trumpists looking for answers and new leadership might just be baited into this.
