I'd argue not all slash equals porn either - a lot of it may begin with the sex but includes so much story that it becomes regular fiction with sex.

I see the point about acceptance, though I think the increase in open fandom in general has helped as some aspects of fan culture can be said to overlap queer/trans. And maybe this point needs to be made more clearly because decades of Spock/Kirk has yet to counter the intense homophobia and sexism of many comic book guys
