Yeah. Especially at the top. But point was that however applicable the “hillbillies in Tennesse” stereotype was (and it was never particularly applicable, 80’s and 90’s Pennsylvania had the highest number of KKK chapters and hate groups of any state). Its definitely doesn’t apply to the alt right.
The better comparison point for the Alt Right is probably the Tea Party. Which was very old, and most dominant in Rural areas and your expected red states. Though many Teabags were pretty well off (is the owner of a construction company with 3 homes and a brand new luxary pickup really “working class”). You were seeing a lot of blue collar workers, unemployed people, and retirees from public sector jobs or fading industries. Educations levels were mixed, but a lot of people without college, or higher level degrees.
The alt right by comparison are endemic in silicon valley, is mostly college educated, is made up of white collar workers or people who expected to be white collar workers but aren’t. Tech and other high demand, skilled work seems over represented. And the vast bulk of them are younger and more “respectible” than generally expected for hard core right wing movements. Hence all the navel gazing “what happened to this nice boy to make him so edgy” bullshit.
