And the left is aligned with the Muslim Brotherhood and other such Islamists because... because these Islamists are the most militantly anti-West? Is it ultimately as simple as that?
I have been trying to understand the left’s ultimate goal. I imagine they think that once the Islamists destroy the West, that communists will somehow march in (how? from where?) and take over the ruins and impose utopia. I also imagine that the more naive leftists imagine they can share power in a West that is taken over by Islam - sort of a hybrid dictatorship that is half Islamic Republic and half People’s Republic. Neither of these make much sense or seem very practical even for a communist. However, this makes perfect sense if you are an Islamist and you are using leftists as useful idiots.
If you look at any cause the left claims to champion, but if this cause gets in the way of Islam, suddenly to the left their cause is forgotten and Islam is preferred. The left champions gays and women, supposedly, but the left ignores the plight of gay people in Islamic countries. The leftists in Western countries visciously attack any feminist who appears in a Muslim country. The left claims to support ethnic minorities but if Islamists attack some minority, the leftists will ignore it or even express solidarity with the Islamists. I think the left is basically run by Islamists or Islamic sympathizers when you look at their leadership, but most leftists are in denial or are too ignorant to see that the left as a movement has for a long time been co-opted by Islam.
The same 1968 Communist revolutionaries liked the black separatist Panthers and Nation of Islam. They are quite willing to side with patsies and muscle that will help them to tear down Western civilization.
