Alright man, I hate Reagan more than about anyone I've ever discussed him with, but this is some inflammatory bullshit. There's a select few people you can realistically compare to Hitler, and they all ordered mass detainment/encampment/executions of people.
Reagan caused a ton of societal and economic damage. All of which could of easily been rolled back if the American people just voted that way. He didn't turn the country into a fascist dictatorship and declare things. He didn't act alone. Reagan was a horrible racist piece of shit, but he was just the face of the republican parties will. Not a genocidal maniac.
