My take on the ‘Leftism’ in the West:
1) It’s ’boutique leftism’ for the better-off White liberals, a typical example is Louise Byrant, the widow of Jack Reed, later wife of the 1st US ambassador to USSR (a very rich man),then finally died a drunk. The tag ‘progressive’ is like a French fashion label.
2) In many ways, it’s xeno-transplant of Christian self-righteousness. As I mentioned before, go ask them why legalizing gay marriage is progressive but legalizing polygamic and polyandrous marriage is not. I also said Judaism, Islam and Hinduism are more vehicles of racial/clan/caste/ethnic interests than as ‘religions’ and that makes Christianity, particularly the Protestant branch, a more ‘universal’ religion than the rest and makes ‘missionary’ work easier. Marxism itself can be considered an atheistic version of Christianity with its own prophets, good and evil, paradise, and what nots. Such an ideological complex could become handy tools of Western powers.
3) Of course, it recently also became a useful distraction from real issues. Queer CUMmunism is definitely more preferable for elites to revolutionary Communism that fights against Western imperialism.
