Truscum is usually hostile against nonbinary people, usually pathologizes transness (dysphoria as a proof of validity), is usually highly assimilationist and usually favors some form of medical and legal gatekeeping, but some of these may be softened up depending on the truscum in question.

Requirements to "fully" transition, to be straight or to buy into the claim that you actually are or at least used to be your AGAB are rarer nowadays, but they're still around.
