I was watching some video and there was mention of someone getting 1984. Upon which, a guy said that this one (one who got 1984) will end up being radicalized. I was already born into a very radical environment so no needs of books to radicalize me (although I am trying to be moderate and chill now)


Because it is the correct use of the word. It is the american conservative propaganda machine which gave it the negative connotations.
Being antifascist matches at least two definitions of radical: “Favoring fundamental change, or change at the root cause of a matter” and “(slang) Excellent; awesome”
