"I think you can be a slash (m/m) fan and be a feminist. I don't see how it's an automatic contradiction."

I do think the secret is badly worded (and it was probably by someone who hasn't had these discussions much) and have thought so since I first saw it last weekend, but, while it seems to be anti-slash-or at least, against using female characters and fictions poor treatment of them as justification-it isn't condemning people for liking it, just saying that the two don't go together. Most people wouldn't want hot sauce on their ice cream, but that doesn't make them natural enemies, or mean that a person can't like both without being a hypocrite. "Not feminist" isn't the equivalent of "anti-feminist," just like "about women" doesn't automatically equal "feminist." The fact that two things don't automatically go together doesn't make them natural enemies.
