So how can you define that any given trans person is "faking it", aside from them literally coming out and saying "I'm actually cis but I'm pretending to be trans for cool points even though trans people are dehumanized pretty much all around"?
They outright said they didn't experience dysphoria, but still considered themselves trans.
People mean different things by dysphoria. For some, it means an intense negative feeling associated with their gender. For others, it's just a preference to be treated as another gender. Usually, when people say they are trans but "don't have dysphoria" they mean "I can live with my ASAB but would be much happier with another gender". Which is, y'know, still dysphoria and still a good enough to say you're trans.
(like, given the diagnostic criteria for gender identity disorder, it's really really hard to say you're trans and not qualify. Asking that people use different pronouns for you is halfway there)
