While i'm not fond of Christianity, I don't believe in this narrative that Christianity is this long con played by the Jews. Christianity if anything, was a primary source of antisemitism for most of European history as Christians blamed the Jews for killing christ. The Catholic Church directly stood against liberalism, marxism and the Jewish agenda at least till 1945. After that, it was infiltrated by Marxists and CIA and it was more or less forced to bend the knee to America to protect itself from communism. The Orthodox church otoh, to this day serves a bastion of traditional values in Russia and Eastern Europe.

The Protestants are however....a bottomless pit. Its not surprising that they are that way, since they jettisoned any objective authority and became religious engineers. Every conman, king and lunatic set up his own little sect. Its hardly surprising that the Jews invented their own little sect, ideal for breeding shabbos goyim and popularized it through the mass media they controlled
