Yaoi is not a fetish. It's a genre. The name is an acronym which translates to No Plot, Climax, or Hidden Meaning.
The name Fujoshi is like the name Brony. You don't have to be a Fujo to be Fujoshi, just like you don't have to be a Bro to be a Brony.
This board is named after the genre. But it rarely hosts yaoi, being little more than a 2D Gay art general for the last 10 years because we have shit moderation. Judging by the social ineptitude here, I'd say the board's demographic are a bunch of Asperger's that'll get defensive when you point out their inability to look past the surface layer of things.
