I mean, the Irish Maoist influencer Paul Morrin (the person behind Marxism Today) did this constantly and then other leftist content creators do the same thing with him (like Hakim and Second Thought).

Honestly this is a bit too much purity testing for me. Person A platforms problematic person X, okay, criticism warranted. But is person B also guilty because they platformed person A? ...If so, where does it end? How many degrees of separation before you no longer assign guilt by association. Have you heard of the Six Degrees of Kevin Bacon game?

I fully agree that we shouldn't tolerate reactionary views in leftist spaces, but there is such a thing as critical media consumption. We cannot shut ourselves in a bubble. If i were to only listen to people i agree with 100% i would probably only be listening to myself. There are takes i don't agree with and find highly problematic in a lot of leftists, even some of the most progressive ones.

Take for instance the Ukraine conflict. A lot of leftist media figures who are very good on issues like Palestine, decolonization, anti-capitalism, etc., perhaps even on China, can still have wrong (in my opinion) takes on Russia's SMO and do not recognize its anti-fascist character. Because they are misinformed or because they have certain biases. But it is still valuable to listen to many of these people for their other correct takes.
