Yeah, but totalitarianism is directly incompatible with capitalism, not to mention the fact that it's just evil. When has totalitarianism not resulted in mass killings? When has capitalism?
"I was a businessman doing business" is funny on its face, but Trump is a businessman, and could not have reached the heights he's gotten to if he was living in a totalitarian state. The "MAGAts" as you call them (it works as a pun, at least) don't really understand the candidate they support.
I will add, I can't believe I'm doing this well in an internet debate. Normally I do way worse.
