trying to attract attention, feeling confident in their looks or simply cute, there are many reasons they might've posted that. Even if it was only meant for attention (which it likely wasn't, posting on a niche community on a small instance on an obscure platform. posts on unixsocks are mostly by queer people for other queer people), that'd be no different from the millions of other posts in communities like Roast Me or Gone Wild.

Why do you say guys can only like this content if they're ignorant or have a fetish? There is nothing strange about liking feminity, and for that it doesn't matter if the OP is cis or trans. This is exactly the sort of harmful stereotype I was talking about earlier. Trans people are not trying to trick anybody, but just live their lives.
