The analogies between what Horowitz is describing and the current moment are striking.
Vietnam protests = pro-Hamas protests
Black Panthers = the BLM. Back then, it was just as fashionable to find some black gangster and worship him as a martyr for revolution
AIDS = COVID. A virus that was dangerous to a very specific group was presented as equally dangerous to everybody causing many unnecessary deaths.
Gay men being physically eliminated through a concerted campaign of ideological lies = transing away the gay.
The same slogans, the same bizarre ideas. The same Anthony Fauci, even. The only difference is that back then the state apparatus wasn’t as completely coopted (and the business world was very marginally coopted) by left-wing radicals as they are now.
Mind you, Horowitz wrote Radical Son a quarter of a century ago. He wasn’t trying to make analogies with 2020-24. Time made them.
