Side point but I'm like 80% sure PSL has nothing to do with that documentary.

It's a great documentary tho. Members / adjacent members of PSL have made their own really good short and long-form documentaries too, like gaza fights for freedom, how palestine became colonized, several great ones on venezuela.

You're likely just encountering the standard "communism and communist parties = bad" in a lot of english-speaking spaces.

PSL has been around a long time and it'd be insulting if anarchist and other ultraleft groups didn't accuse it of everything under the sun (that they usually accuse each other of also). But because it practices demcent, and isn't some trotskyite or anarchist sex cult, It's not been shown that national or even any branch supports abuse.
