It was fitting that John Waters performed his one-man show, This Filthy World: Filthier and Dirtier, at the inaugural horror-focused Shock Pop Comic Con in Fort Lauderdale. And on Valentine's Day.
The obvious was the ironic pairing of very unsexy sex jokes being told to a crowd of horror movie fans on a day dedicated to romance. The less obvious is that Waters has always put those on the fringes of society on a pedestal. He doesn't sensationalize the differences; he admires them. His work, much like this comic con, makes the "horrific" human.

Cons generally attract those who maybe once were the nerds of their classes but now are kinda cool. They've found a community of same-minded people with similar interests. When they dress up like some mystery-to-me anime character, they're imbued with a sort of power. Much like the wonderfully weird freaks in classic Waters films.
