I don't see any reference to Harvard on Donald Trump's Wikipedia entry.
Donald Trump - Wikipedia
As I understand it, Harvard students want any Harvard alumni who have worked with/for Donald Trump to have their diplomas revoked.
There seem to be a lot of vindictive idiots on the Left. It's not so long ago that people on the Left were calling for those who worked for or supported Trump to be blacklisted so that they could never work again. Let's not beat around the bush, these are tactics that are intended to silence any dissent. If you don't comply, you and your family will die cold, homeless, and hungry, through lack of work and income.
There are laws in civilised countries, and if you break them you can expect punishment, but being of the wrong political inclination is not, and should not, be a crime. Why do people on the Left so often seem to want to create some kind of para-legal, and para-judicial system for punishing those that they disagree with? You can call them idiots, or stupid, but I think that's a rather lazy and inadequate argument for something that keeps cropping up again and again.
