Yes that seems to be the most basic quality in humans the desire to create a group that every one is allowed to exploit and ridicule. I see it even in fantasy movies and literature, where old racist and antisemitic canards are dug up and applied to some non-human rubber creature from another planet, as if the writer/director needed someone to apply them to and picked the nonhuman since they could no longer apply it to a human. Why use them at all? In some realistic movies nasty statements are applied to poor white people "trailer trash" as if no one could go through a movie without denigrating someone.
