To my knowledge of the reign of terror, the majority of people killed were the working class, peasants, followed by the middle class — for a series of killings seemingly only pointed at the bourgeois that certainly seems indiscriminate.
If you participate in a system that punishes people with violent retribution indiscriminately, that violence will be visited upon you inevitably. Randomly killing politicians will not solve anything, and I'm not about to detail what will on a public forum. You can take that however you will, I'm not about to continue arguing with blue MAGA.
Edit: oh, and no — I'm not of the opinion that a reign of terror will happen. I think something worse will happen.
