Of course he did. He’s just the typical caveman Republican. Their answer to anything they don’t like or don’t want to deal with us to kill it. Like whatsername shooting the inconvenient dog that she couldn’t be bothered to train or find a home for. Repeat shoplifter in jail for the 5th time? Just execute them, waste of jail space. Country full of brown people of a religion they don’t like? Just nuke it. Migrants crossing your property trying to get to the US out of Mexico? Just shoot ‘em. People whose politics they disagree with and find annoying? Shoot them too.
I think the narcissism is a compounding issue, not the driving one. I've talked with many Republicans and far, far too many of them see harsh punishment as the answer to everything, and of course the ones that want to expend the least effort thinking about some issue or dealing with people like protesters or BLM just say that they should be shot, run over, etc...
It's beyond narcissism. It's closer to psychopathy, those that agree and help further that agenda are sociopaths. The lock-step voters? A blend of spectrum B personality disorders. Rittenhouse, likely sociopath. Average run of the mill y'all queda? Somewhere between narcissist and sociopath.
