This time-tested white-person maneuver may seem so awesomely useful to you that you are tempted to go out and try it right now. Not so fast. White people have spent the last 30 years perfecting this technique. There are cultural guidelines.
It’s also critical that you avoid the fatal mistake of getting creative and comparing people you don’t like to other evil dictators, such as Joseph Stalin or Fidel Castro. With few exceptions, white people are actually fond of almost any dictator not named Hitler, and your remark that “this is just like something Mao Zedong would do” will be met with blank stares and possible social alienation. This is because, with the exception of Hitler, oppressive dictators share a passion for many of the things white people love — such as universal health care, conspiracy theories, caring about poor people while being filthy rich, and cool hats. Stick to the script and compare things you don’t like to Hitler, and Hitler alone.
