Apparently, that group worked with the Nazis during WW2, but "this Order granted Gorka's father, Paul Gorka, their title in 1979 in recognition of his resistance to the post-war Soviet occupation of Hungary".

I mean, he's a troll who is intentionally offensive, but either Slate doesn't know what they're talking about or they're lying. One thing he isn't is a white supremacist.
And Seb Gorka? According to his Wikipedia page, his father, Paul Gorka, was awarded a medal by Vitézi Rend in 1979 "in recognition of his resistance to the post-war Soviet occupation of Hungary". Slate seems to consider that evidence that he's a Nazi.
