“Jews have associated themselves with left wing parties and even communists movements for around 100 years at least”
It would be helpful for your understanding to understand the various “waves” of Jewish immigration to the USA.
Not all are the same, both religiously and from most recent country of origin.
The liberal wave you discuss (now the Deformed) was later overtaken by a more recent wave of Conservative and Orthodox Jews, largely from the Soviet Union. They understand liberalism very well.
And, perhaps out of Tribal forgiveness, I tend to give the earlier, misguided, Jews of the first wave a break, in that their choices in Europe were “Nationalism” (which was stridently anti-Semitic) or Communist/Socialist (which told pretty lies about such things and, above all, promised not to treat Jewish people badly if they were reliable servants of the State).
Excellent post. Please see my post # 48.
