Anyone who thinks that Trump is a violent authoritarian clearly wasn't looking at the four years he was in charge with a critical eye.
Even with respect to the vaccines, he didn't mandate anyone use them, he just helped get some red tape out of the way so that they could get to market faster. It was others who took the fact that those vaccines existed and then mandated that millions of people be forced to take an untested experimental vaccine.
I know myself and a lot of other people kind of wish that he had been a little bit more of a violent authoritarian in certain respects. If Minneapolis was my home city, and a bunch of violent lunatics were burning it to the ground for months, I would want every level of government to be stepping in to protect the property rights of the individuals other than the protesters who live in that City and are watching their homes and businesses be burnt to the ground. Instead he just sat there wagging his finger at them.
