It's quite hard to credit in what is meant to be the "free" west that it turns out free speech doesn't exist
Hmmmm...it's a big topic. I'm not sure it's that simple.
Let's assume there was a period through the 20th century where "Free Speech" was a core value in the West.
That was driven by two things, one laudable, one less so.
Laudable: the experience of totalitarianism in Nazi Germany, Communist countries in Asia and the Soviet Bloc, and the utter horror of allowing that to happen again.
Less laudable: "Freedom" becoming a - I guess the best word is "brand value" - of the West in the ideological struggle with its political enemies. Not an actual commitment or valuing of free thought, messy as it can be, just using its fragility as a tool/threat to keep your population patriotic.
But the ability to wield free speech, to take part in any public debate and have your voice heard, was not equally bestowed. So the insight of Wokeism, when it is at its best, is that the West's "Free Speech" has often just been the freedom of those with power to say what they want about those without. Hence the Woke emphasis on "Lived Experience". Because the voice of someone who has experienced a thing but does not have the power to state their opinion loudly and confidentiality should not be drowned out by someone who only has a theoretical belief but has the confidence and power to state it loud and proud.
I remember Boris in his heyday with his Oxbridge debating society confidence in saying the unsayable and arguing either side of the argument and I remember thinking it's easy to be that "dispassionate" voice when you argue about things that never actually touch you or threaten you.
And I remember arguing for deplatforming when it was about what to do about holocaust deniers, and that lies can be told a hundred times faster than they can painstakingly be disproven.
I'm not sure what my point is here, but as my experience as a gender critical woman brings me more into the orbit of (for want of a better description) the "unexamined" right wing, I do worry that the loudest voices for free speech are the ones least inclined to consider how that speech may be limited implicitly by lack of social power to ever even try to raise a voice at all.
