re: Explain to me the Left’s love for both Islam & Communism…

It is an ideology that they have been given that fits their ideals of victimhood and entitlement. Someone owes them something, and it is not their fault that the majority of them are worthless losers who may have gone to school to get a degree in "economic studies of social influences for indigenous peoples".
They would benefit from a system that takes from others and makes everyone miserable since they themselves are miserable.
