Yeah, wow. I went down the rabbit hole on Bernie Bros the other day and was thoroughly dismayed.
Read a book written by a mate on China's New Red Guard - which is the movement in China to bring back Maoism, the Cultural Revolution and all that silly shit. The parallels between the Trumpist right, Bernie Bros and the new red guard are unbelievable. They are nationalistic, conspiracy believing, base their beliefs on annecdotal evidence over science and rigorous thought, respond with anger and aggression, ad homeneim to hell and back, etc. etc.
It's all the same movement of arrogance, mixed with internet anger with a dash of Dunning Kruger. I really wish I knew more about the 1930s as I'd love to look at the parallels in terms of social behaviour, the rise of print media, nationalism and industrialism alongside the internet, globalisation and modern day nationalism. There may be no comparison, I have no idea. Seems like an interesting question though.
