Secular progressive Jews are universalists. This has been true since the advent of Socialism and Communism the late 19th century.
Universalist (i.e., Communist) Jews were out to destroy all cultures, ethnicities and nationalities, not just their own. Psychologically, one can understand this somewhat. Having shed their religion and religious trappings in order to become enlightened and assimilated they discovered that the greater society was in no mood to accept them despite their apostasy. Indeed antisemitism was becoming fashionable precisely as a reaction to the massive Jewish assimilation that was taking place throughout Europe.
Hence, for such Jews, if they couldn’t gain admission to the club they would destroy the club – all clubs including the Jewish ones (synagogues). In Russia, Jewish Communists were especially vicious and enthusiastic when it came to destroying the latter.
Today’s secular progressive Jews are also universalists, but of a different sort. They are against only their own particularism – Judaism/Zionism – while championing the particularism of everyone else – Muslims, Latinos, Arabs, Iranians, Somalians, inner city mobs; indeed any group that can harm America or harm Jews or, ideally, harm both.
As such, they often employ Jewish tropes to justify their activities even as they militate noisily for the destruction of the Jewish People and the very America that gives them the freedom to pursue their culturally and ethnically suicidal dreams.
Yes, they are consummately disloyal. To themselves. In so doing they are putting the rest of us at grave risk.
