What do those things prove? That there was always some distrust. But from what I'm seeing online, after Trump came onto the stage, every negativity grew louder. Racism, hatred, prideful ignorance, anti-intellectualism, etc... all of it together.
I don't understand what you are trying to say, that Trump was cunning and purposefully told his followers to do things that would get them killed during COVID despite knowing better because that somehow benefitted him by fanning the flames of anti-intellectualism? You're saying that he would have lost support if from the very beginning, he told everyone to take the virus seriously and protect themselves with masks, hand-washing, and distancing when in public places? They would have thought he was a loser or something? Because the entire idea that doing those things made you a loser was invented by Trump.
