If there is one thing that the last few years has taught me, it is that we need diversity of thought.
The woke (for want of a better term) idea of progress regarding EDI, where everyone looks different but thinks exactly the same (and where those who deviate from the list of right-think are Nazis) is the exact opposite. The one area where diversity is not accepted at all is thought.
So, I think that for better, or in some cases for worse, we as a society need diversity of thought. We need freedom of speech so that people can articulate those thoughts.
Now, most of us agree that making a credible threat to someone's life or incitement to violence should be where a line is drawn. Once you cross that line, there should be Police involvement. However, everything before that line (including things that I would not say myself) should be allowed.
The authoritarian approach is worse. Much, much worse.
