i know you tried to sound smart there but your first paragraph is nonsensical, jsyk
“type of person” is too broad to make your question valid. depends on what “type” means.
if by type you mean facial features and color of skin, eh sure, why not… even though it’s less that and more about justifying oppression for power and resources.
but you used it in the context of acab, in which case type means what you do for a living which is entirely different from skin color… so no. you can make such judgments, and it wouldn’t be racism or even have remotely similar thought process (say, as you could point to sexism, homophobia, etc as at least having some parallels in the way of thinking).
so yes, i can say all cops are bastards, all vulture capitalists are monsters, all landlords are leeches, all billionaires are immoral, all republican politicians are demons…
