Listen if Hitler is the only comparison you think people understand, and you think the only way to convince them that a thing is bad and should be avoided is because, like, Hitler, and because in some racism dream where you get darker than you are and a bunch of majority culture white rednecks confuses you for a terrorist instead of just a normal american of partially Syrian or Italian or Mexican or native American or Guatemalan extraction that's fine. Call trump Hitler all you want. You won't be the first, and apparently you have a fellow traveler as a professor at MIT. Just don't expect me to take you seriously. Not when you're comparing Trump to Hitler for putting a hold on visas of students from a country whose official policy calls for the destruction of Israel and which is actively hostile to the interests of the united states, and who might facilitate potentially dangerous technology transfers to same. Though for the sake of consistency, and to seem less partisan, you may wish to consider similarly comparing Jimmy Carter to Josef Dzugashvili because he put a much longer hold on Iranian student visas in the late 70's. Your call.
