Collectivism is anti-God, anti-Torah, anti-Jew, anti-masculine, anti-man, anti-boy, anti-independent, logical thinking, etc.
You are are right. Many of the most prominent proponents of collectivism were Jews, but they were self-hating, atheistic, secular humanist Jews.
Jews are leaders in anything and everything good, bad, or indifferent, because that’s what God appointed them to be - to lead humanity closer to God.
And Karl Marx’s father converted the family to Lutheranism, so as to help with their assimilation and Germanization. For example, Marx pere changed his name from the Jewish Herschel to the more Germanic Heinrich. In other words, the only thing Jewish about ol’ Karl, is his ethnic background.
