I’m not sure that’s at all accurate. ‘Nazi’ connotes a pretty narrow grouping which (inter alia) held that Arians were genetically superior to all other races. I’m not sure many of these out in the streets would subscribe to that view. ‘Nazi’ is a pejorative term that has been deployed far too glibly when describing the far right.
I think the terms criminal, antisocial, simplistic, racist, easily-manipulated, indolent, selfish, inconsiderate, incoherent, feral, (in the main) sinfully stupid and very, very badly dressed paint a far more accurate picture.
