Whether you like it or not, yaoi and yuri are fundamentally part of the Anime community. You can’t remove it. (Though white washing it out of American translations of manga and when dubbing anime into English has been tried.) It is not going to go away. So if you’re going to run an anime convention, you have to deal with this reality. Unless the event is explicitly billed as a child friendly event with no adult content allowed, members of the anime community are going to expect that yaoi and yuri are going to be tolerated.
Sadly, Animethon‘s organizers failed to get this message. Rather than claim to be a convention that is child friendly, the organizer decided that the convention would be anti-yaoi by prohibiting same sex kissing for cosplay events on stage. Heterosexual kissing was still allowed. She wasn’t discriminating against gays and lesbians because she has gay and lesbians friends and she likes them. (Thanks but no. That’s a cop out. I have Gay friends =/= I am tolerant. It is insulting to our intelligence.) When called out on it, she finally decided to allow same sex pecks on the cheek because heterosexual friends of the same gender give pecks on the cheek. That’s her ode to tolerance. Makes her a special kind of fandom snowflake where heterosexual same sex kissing is okay but homosexual same sex kissing is not.
She then spelled it out quite clearly: Animethon is not the place for large population in the anime community who like, read and watch anime and manga. If you want that, go to Yaoicon. (Because anime isn’t about the gays and lesbians and yaoi and yuri.) Frankly, I think that’s a good idea. If there is anyone in Alberta, Canada thinking of going to Animethon, don’t and tell the organizer why.
