If we don’t stop it, it will end in atrocity…against PoC, most likely. Right now, we’re still in the “They are a threat to us”, stage.

If you’re asking what they’re next step will be, that is open dehumanization of poc. They will declare us to be (make up a word, use an old one) and use that, and the threat of their imminent extermination, as an excuse to engage in the violence they always wanted. That has, historically, been the tactic.
