@Lilliwyt:
I mean, the girls here
don't only read BL. They'd been writing seinen manga, that's almost as far as you can get.
If you're referring to the fact that they sort of seemed to joke about BL being for brain-dead people—that's not actually the intended joke; it was a pun on "fujoshi" (lit. "rotten woman", which is itself a self-deprecating pun on a different word pronounced "fujoshi" that more or less just means "woman").
