I sorta get where he's coming from, but he really ain't driving right. I have a problem with a lot of slash (or yaoi, whatever) too for unrealism, shallowness and stereotypes, but THAT is the big hint not to take it seriously if you're even marginally sane. Most people don't take bodice rippers seriously either. Not underestimating humans' capability of causing harm to others with their stupid, I think that in the end, people who do believe it's real only set themselves up for disappointment.

And talking about stereotyping, I am everything but impressed by his comparision of top/bottom and male/female as if it's some kind of obvious given. Kinda clashes with the ideology behind his rant.
