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"
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.
real world organizing =/= a bunch of internet dogmatists getting together to march
their local branch announced their formation with a post hashtagged #marx #engels #lenin #trotsky and had a ton of Alan Woods books for sale. they're trots.
Crimea is host to Russian naval bases and a big Russian population, and the bases were leased from Ukraine after their transfer to the Ukrainian SSR and the dissolution of the USSR. When the NATO government was established in Kiev, Russian forces were already in Crimea and clearly weren't going to hand over Sevastopol to NATO.
