The original research dealt with people who could not function in ordinary life, could not use the elevator, pick up a newspaper, or buy food because they feared it might have been contaminated by homosexuals. I would guess this to be a particular manifestation of OCD, rather than a disorder that had its origin in a fear of homosexuals.
They might want to rethink this, if we start claiming homophobia is a disability and they can't discriminate against homophobes.

Exactly. If homophobia is a disorder, then it's also a disability under the law. Homophobes' jobs should be protected, and they might also be eligible for disability benefits. An interesting turn of events.
Great point. Imagine the first ADA lawsuit..."So what if I think gays shouldn't get married! You have to hire me!"
