> They don't call themselves that, they don't organise under that label
Why would they? Much of our current mythology is based around slaughtering fascists in WW2. Why would anyone identify with that?
> their views aren't particularly similar to historical fascism
Hence the appellation of neofascism. There is a direct thread of political genealogy from the alt-right to the OG fascists, through the European Nouvelle Droite (inspired by Mussolini) and including figures like Steve Bannon who used to push the British BNP: a legitimately neofascist party. He also was buddy with Dugin for a while: a confirmed neofascist.
Read some fucking history and get stuck into the thought and theories of the far right if you want to play this game son.
> it's a serious threat!
Finally, we can agree! Look at the escalating far right violence in the US and Canada, and the erosion of the open society in Europe, and the current actions of Russia and China.
