Maybe that's because views that were not long ago considered beyond the pale have been pretty much mainstreamed over the last few years.People increasingly can't handle being challenged in their views, across the political spectrum.
"Cancelling" isn't about stopping other views, it's about marginalising them to the point they aren't tolerated. So you have safe spaces on both sides that become more and more toxic to any form of dissent.
So is free speech under threat? Not quite, because everyone still has the ability to say what they want. The threat is that people are increasingly only allowed to say what they want on very specific platforms based on what I'd call 'a social editorial direction'.
This creates extremism. In the past, people disagreed but they debated and generally accepted if they won or lost the argument. We don't do that anymore - there's no debate, no shades of grey, everything is black and white, right or wrong, and people are willing to die on their own collective hills for their cause, all the time, reason be damned.
And it is extraordinarily dangerous.
Not saying I'm right about this or looking for a row, just putting it forward as an idea. I've not given it a huge amount of thought to be honest.
I find all this "culture war" BS a deliberate distraction from us all being properly shafted. It's divide and rule like never before.
