I think it's important to read Blackshirts and Reds to see why "red fash" is a gross misunderstanding of Marxist movements. You don't have to agree with Marxism, but you must understand that Marxist movements have served the working class, and fascist movements the Capitalist class.

Myself, I am a Marxist-Leninist. There are good Anarchists that do good practice and good work, don't get me wrong, but in this moment sectatian nonsense like "red-fash" splits and divides what should be a more solidified movement.
