I think the best and most fair interpretation of the situation I've ever seen is from Carl of Swindon;https://www.youtube.com/watch?v=hMakM8lUHRI
tl;dw - The Cosmopolitan-Jewish identity is successful and cosmopolitan with a huge sympathy for victims because of the Holocaust. Progressivism is a sickness of the rich inner cities because such people don't have actual problems to keep them grounded and since they can switch between 'Hey fellow white people' virtue signalling and 'Oh you can't say a word about me, I'm Jewish and thus a victim' on a dime, they're unfortunately in a perfect position for bad actors to do as they please.
Do note, this isn't the Jewish identity, this is the Cosmopolitan-Jewish identity, Cosmopolitan first, Jewish second. Said people tend to be atheists in terms of belief and you don't hear about this kind of shit from orthodox Jews with the hair curls or anything for a reason.
So, it's less an ethnic thing, more a cultural thing for this particular subset of people, second or third generation rich wankers that've never had a problem in their lives of any ethnicity, it's just Jews tend to be rather successful and rather Cosmopolitan because they a: Have good traditional foundational values that lead to multi-generational success and b: Tend to work in areas that are very city orientated (Academia, Finance, Politics, Journalism, ect, ect.)
So, pinning it on them being Jewish is a bit unfair, it'd be like pinning the existence of Shaun King on all white people.
