I honest to god think an episode about those kinds of blogs, coming from their bloggers, would be tremendously entertaining and do as much to clear up misconceptions as the Furries and Asexuals did. The people who shriek into the void that they are truly Homestuck trolls and that demisexuals are more oppressed than gays and lesbians likely won't change their mind, but it would make a really handy resource to point to, especially for anyone who thinks they have a friend who's in danger of slipping into that hole.
