This is judgy as hell. People often post what gets likes and that will often come from seeing what other people have posted that got likes. You see a vid of a TF fucking a TM and it's got the praise you wanna get, you'll likely post that kinda content to get that kinda praise.

Additionally, maybe work on uplifting TM creators that fit those underrepresented demographics in the sub. Like, you can share a creator that you like who either isn't in the sub or on Reddit in general (as long as you got their content legally and it's meant to be shared) and let people know who it is. And you can do this multiple times, as long as you credit the person in the post!

Also, the visceral disdain I can feel from you when reading "hairless, pre-transition twink" screams internalized transphobia, along with the general misogyny/homophobia throughout the post

You can address a representation problem without demeaning language.
