Well that's just completely delusional, really. Institutionalised anti-communism has nothing to do with cancel culture today, which entails keeping up with the latest vapid neoliberal take. So much for McCarthyism. I have no idea why you would just randomly namedrop the civil rights movement without elaborating at all, so I am just going to glance over that one. As to the "Satanic Panic", I don't think American Evangelicals have any sympathisers outside their camp, but in all fairness the Satanic Temple literally perform child sacrifice rituals today - yes, really - so perhaps the Evangelicals had a point. The free speech stuff is just complete and utter nonsense, and a total inversion of reality.

As to the snowflake stuff, the extreme neuroticism and emotional instability of American university radicals is plain for all to see. There is nothing that can be said on that topic, there's an endless amount of "liberal meltdown" content catalogued online if you wish to observe this phenomenon for yourself.
