Well, zealot Christians (and organisations like the Inquisition) hated people "for what they did" (e.g extra-marital affairs, being an atheist, not going to church enough, magic spells, etc) not for what they were. I don't see how that's any improvement over hating them for what they are. Hate is hate.

I also have a three digit IQ and I don't believe Eich hates gay people. In fact he has worked closely with lots of them perfectly for ages (by their own admission). He might love marriage too much as a specific, and historically specified, tradition though, which is a different thing.
