Hmm! I suppose that hinges on how you define "fandom". Since my personal experience of fandom does not really include yaoi circles, that's a blind spot of mine.

Since there are enough people with the "yaoi != slash" viewpoint, it's probably worth explicitly covering that rather than implicitly.

Probably worth getting some separate questions and if there's to be any lumping, to do it on purpose.

I'm wondering about some "I consider myself primarily a ___ fan, but I also like:
x
y
z"
questions, too, like het, gen, mixed, yaoi.
