For sure. It often extends to elves and stuff to. "Why are you talking with that DEMI?!" Even though in many instances the demi human races are superior to humans they are still shunned and oppressed.

As much as I like the Shield Hero anime, it really messes with this trope. Raftalia is a beast person slave. But because she's cute and a little girl spear jerk wants to "rescue" her. And then Spear jerk hates Filo when she's a bird but loves her when she's a cute little girl.

I did enjoy Reincarnated as a Sword as it was blue cats and other beast people oppressing the black cats and not so much humans just looking down on beast people. Felt less contrived that way.
