It looks form here that you are so busy trying to justify a thing with in-world biology and metaphysics that you seem to be missing the fact that, to this day, the exact same logic is used to justify real-world racism and misogyny:
They aren't human. They are sub-human. They aren't people. They don't think like us. They are alien. They aren't intelligent like us. They don't feel like us. They have other drives and instincts that control them...
Now, get your head out of your setting for a moment. Think of this from the real-world perspective.
The exact same logic that is used in the real world, is being used on this fictional symbol - that symbol looks like members of your demographic. The portrayal is like those leveled at your own people in the real world.
How the heck do you figure that looks? How are you not trying to weasel word things to be able to continue the same sexism or racism under an excuse of fictionalization?
