Teh way I see it:

Femboy/trap/otokonoko/crossdressing/etc. = fully allowed

Tranny/shemale/ladyboy/newhalf pr0n = allowed if otherwise non-rule-breaking

Trans-related discourse, politics, news, medical shizz, guides, activism, rants, flags, accusations/namecalling, anecdotes, etc. = B& regardless of whether it's pro-, anti-, or indifferent

For teh B& stuff, go to virtually any website that is not Heyuri
