You know you can take this up with him directly, right? If you know his content well enough to first say that you like it, and second claim with confidence that he's a "Muslim first and a Marxist second," you must have heard more than once that his DMs are open.
Why here? He doesn't even participate here. The !leftistinfighting community even states in its description that this place is for directly challenging one another, and yet this post is challenging a specific individual who isn't present.
What purpose is served by posting this criticism here, that isn't better served by posting it directly to the accused?
