While the current climate is not comparable, I find the actions and general attitude of the current US government similar to that during the McCarthy era.
Which led me to this very interesting article from 1965: https://www.thecrimson.com/article/1965/6/17/the-university-...
In it, the author described the attacks on specific personnels and public villainification of Harvard. More tellingly though, the author wrote the article for students in the 60s, who, growing up a mere decade after, most likely considered the events "an aberration which could not have lasted", and that, "the whole [McCarthy] period has an air of unreality".
Those who did not know history are bound to repeat it. Unfortunately, no amount of textbooks and historical resources seems to be sufficient to impart lessons to subsequent generations, and we are bound to repeat it after a few cycles.
