PSL, DSA (not the leadership), and many others are not trotskyist. Also the US only goes after actual threats, trots historically have been the useful idiots for america in every instance.
PSL doesn't call themselves trotskyists but they do the same things trotskyists do: tailing the labor aristocracy, electoralism, nonthreatening protest, red charity, opportunistic identity politics, covering up sex pests in their org, etc.
I guess critique of PSL counts as wrecker behavior on this site, but I'm thinking of when Gloria La Riva tried to brush aside accusations of transphobia and was all "how dare you call me cis, I'm a woman of color"
