The Mezzanine

Yes, he's in a tiny minority, but is that because the real loonies have moved on elsewhere? Our fandom is now too small for most berserkers? (Not entirely sure I'm sad about that).

He does seem to express those bonkers ideas pretty consistently, but that may be because most BtVS fans are at least socially liberal. In other contexts perhaps he's pro-gay?

No, I don't think that's very likely either.
