It’s a standing joke that the most homophobic ranters are likely to turn up in the news some day getting their luggage lifted. As it turns out, though, some of them face a fate that’s even sadder.

Remember Jonathan Katz, the physicist who briefly held an advisory position with the Obama administration until his online essay declaring that he was proud to be a homophobe made the news? He raved about how homosexuality was simply disgusting and people with “unnatural desires” need to learn to repress them, for their own good and to prevent disease from spreading through the population.

Surprise, Jonathan Katz has not been exposed as a practicing homosexual. Instead, his son Isaac has come out publicly as a homosexual.

The elder Katz is going to have to learn something now, which is a good thing.
