I don't think you can get much further right than he was though. When I hear of all the stuff he was saying. I don't think even Trump has ever said some of that stuff. Like that women should be secondary to men.
Apparently he also said that "a few deaths a year are a small price to pay for access to weapons". I wonder if he still felt that way knowing what was coming. I don't have the source link to hand though. News goes so fast now and I don't archive everything.
Personally I'd never heard of the guy but I'm not in the US (and very glad about that right now, the country seems to be tearing itself apart)
PS Also I'm not trying to defend the far right, I'm very left (especially by US standards which doesn't really have a 'left' compared to Europe, liberalism here is a moderate right-wing thing). But murder is definitely not ok in my book, of course. I would grin when I see a tesla dealership graffiti'd or a "swasticar" or "from 0 to 1939 in 3 seconds" poster at a bus stop. but that's about as far as it goes. You don't touch people ever. Or really destroy stuff of value.
