first off, GTFOH with "wannabe". you're a wannabe gatekeeper of gender-affirming care.
gay identity absolutely is not more, or less monolithic, than trans identity. anyone who knew anything about gay people would know that gay identity is diverse, sometimes fractious, and anything monolithic. a straight guy looking in at queer people is the last person who should be telling queer people about their identities.
you also fundamentally don't understand dysphoria. the idea that people would happily take a pill to feel like a cis man/woman is both ridiculous and offensive. your description of "conversion" is also wrong. you entirely ignore - unsurprisingly, bc you are quite ignorant (yet, in true toxic masculinity fashion, feel comfortably authoritatively proclaiming on) of queer people - the fluidity of both gender identity (i.e. non-binary, genderqueer, genderfluid, etc people) and sexuality. GRS as "conversion therapy" is a pure, and absurd, TERF/GC line, as well as also being offensive. actual conversion therapy is a terrible practice forced on gay people by religious fanatics; its equivalent is the kind of "exploratory therapy" proposed by GC ideologues like Stella O'Malley.
finally, why exactly are you browsing trans forums, and trying to clock them on dating sites? this is the kind of thing you see on Twitter all the time - (cis) people whose entire lives seem to revolve around obsessing over trans people. like, why are you obsessed with this particular issue (or this and anti-vax nonsense I guess)? for me it's life and death for loved ones and community. what's your deal? (not implying this either way here - I have no idea - but I'll note that this kind of obsession, unsurprisingly, often goes hand-in-hand with a closeted attraction to trans women, to the point that it's its own stereotype)
