It's the practical erosion of Free Speech. Liberal (small "l" liberal) democracy and liberal science thrives on members: 1. Being willing to admit they may be wrong 2. Having access to a diverse information diet But the past two decades have shown erosion of not only legal Free Speech, but practical free speech: * Whereas previously they were just ignored (or even rebutted), today employees, students, and professors…
1. In the past, the wrong speech would result in both government, and private sector censure. You're selectively omitting the civil rights struggle, the communist witch hunts, the german witch hunts that preceeded them, the history of internment and concentration camps in this country, the suffrage struggle...
We didn't somehow magically arrive at the world of 2020, without a lot of people being punished for their speech.
2. Our information diet was never as diverse as it is now. Media, prior to the age of the internet, was much more of a monoculture of ideas than it is now. New, radicalizing information arose in university halls and books and rallies, not on the television.
3. People are no more, and no less willing to admit that they were wrong today, as they were in the age of, say, segregation-forever Jim Crow south.
This coup is not the result of offensive speech being restricted, or hurt feelings. It's the direct result of a few people with media and political influence actively directing their followers to undermine our democracy.
This could have happened in any decade - but it happened today because of the particular personalities involved. You elect a president that is very vocal about his lack of respect for the law, the election process, the presidency, or democratic institutions, and this is what you get. The only reason it is happening in 2020, and not 1920, 1960, or 2020 was because the personalities on the ballot in those years had respect for those things - or at least, were adults who managed to check their worst impulses.
When he said that he won't accept the results of any election that he didn't win (back in 2016), do you still think he was confused, or kidding, or misunderstood? He was just being honest. You can't let people who profess such ideas within reaching distance of political power, because they will happily burn the world down around them to retain it.
