there is nothing socialist about ethnic nationalism. that is the definition of far right extremism.
it is extremely important that actual leftists confront these people when you see them on the ground and tell them they are not socialists and don't represent the left, but are fascist foot soldiers advancing the politics of the far right. at best these are progressives/conservatives, but most of them are open fucking nazis.
no leftist would support these far right islamist political organizations on the grounds that they are vehicles for ethnic nationalism. that makes no sense at all.
we need to take our streets back and chase these fascist scumbags polluting them back into the gutter where they belong.
