Tendencies are not exhaustive lists of policy positions. They are identities, or "Cliques". Someone who calls themselves "Just a Marxist" might have the exact same sets of beliefs as an "Anarcho-Hoxhaist" and neither one is necessarily wrong, in much the same way as people with the same objective gender experience might identify as "Effeminate Man" or "Nonbinary Trans Demigirl".
Maoists tend to not like modern China (it's "revisionist") or the post-Lenin/Stalin USSR but are otherwise model revolutionary Socialists, usually. Trotskyites are a mix of Stalin-skeptic Marxists (reasonable, even if I don't agree) and "Democratic Socialists" (i.e., anti-Revolutionary Socialists) who just really like Trotsky for some reason.
If anything ends with "Thought", it just means "I like the cut of this guy's jib!".
