Trotsky himself considered the USSR a "degenerated workers state", and spent a good amount of his life advocating and working for itts overthrow, notably with the western powers. Trot groups followed this pattern.

They also hilariously think that lenin's testament meant that trotsky should've become king, not realizing that he lost that crucial vote to Stalin, and communists don't appoint successors like monarchs.

That's why nearly trot groups end up being leader/domination/sex cults.

You'll get good answers on the history of trotskyism over on lemmygrad.

Also watch that video. It's from a pakistani communist and former trot, who has extensive organizing history with trotskyist parties.
