On the violence front, just a few days ago, Trump threatened to deploy active duty troops on protesters marching for a George Floyd. This was such an egregious action that Trump’s own former Secretary of Defense and one of the most regarded leaders in the military to denounce Trump as a threat to the Constitution[1]. Those were his exact words.
Trump has called immigrants animals, he secretly separated immigrant children from their parents at the border, he’s constantly calling for investigations of his political rivals, numerous types of behavior that we’ve never seen in a democratically elected leader before. If you’re not understanding the accusations of “coded language”, I’d encourage you to read up on the history dictatorships, because authoritarian behavior (deploying troops against peaceful protestors) and dehumanizing speech (calling immigrants animals) have preceded every single genocide in human history.
