I hear you, but everything on the left was, more or less, an outcome of the Jewish belief system and its effect is to tear down and destroy the Christian West. Whether it was done with hostility in mind or just wanting to promote a better world under Judaism is another question.
I found an interesting paper that makes this point.

I’ve read Kevin MacDonalds books and they are laughable. A relatively recent leftist ideology that is limited to specific groups of Jews and leads to negative population growth through intermarriage and low reproductive rates is the opposite of a group evolutionary strategy. MacDonald knows nothing of Judaism, Jewish history, Jewish groups, of intergroup dynamics between Jewish groups. And his theory is self-negating garbage.
