There's the Alf Garnett factor in England. He was a white, cockney, working class fascist (television character) who played straight into the hands of white, cockney (and the rest) working class fascists. On one hand the irony worked but on the other hand it was manna to the fascists who quoted his catch phrases as gospel. He hated 'coons' etc and I often thought the only people to benefit were the white, working class, cockmey writers who were applauded on both sides and no doubt laughed all the way to the bank.
