An error in my thought? I was responding directly to something you asked:
What would you think of Biden or Trump calling our military to put down protests like what happened in summer of 2020 in the U.S.?
They do this and that's bad. Your "hypothetical" implies you didn't think it was happening, so I pointed out it is happening. There are examples all throughout the last century in America: Kent State, when Reagan used the military to go around the air traffic control unions, the battle of Blair Mountain.
