I think it's a case where, quite seriously, I've seen dozens upon dozens of gay mens' gaydar go off when he speaks. Maybe he's not, and I'm sure the theories that his motivation is scorned-loverhood are way off base. Closet case may just be vengeful thinking, but there IS such a thing as gaydar - and it often works.
In any event, the Daily Show had the best run-in with Shirvell. He did not seem to get that he was the brunt of their joke, and he's an idiot as well as a closet case.
It's a very funny piece, and the place that seems to come up first on a google search to view it is
here.
Enjoy.
