What Kant, Locke or Hobbes imagined has only little to do with current societal environment. Our politics and structures are global and the age of internet has mixed it even more. The religions and christianity especially tried to control everything was said under their hemisphere by controlling who could print books or distribute them.

The european (or EU in this context) is truly multinational representative political instance (not a government). While it provides lots of opportunities and lets voices from dozens of different cultures to be heard, it also makes decision making hard. The opposite way to rule is authoritan or totalitarian way where there is just one ruler who has not real opposing forces. In that light you could argue that while EU is large political and economical alliance, it also fails to satisfy every political need of it's elected members.

what US is showing that less there is political variety (powerful parties) less there is moving space for expression, freedoms and change.

As a person who has masters in politics, I appreciate the fact that you brought Kant but more Hobbes and Locke into this. They are excellent reference point for those thinking about origins of societies and liberties. John Locke would have hate everything what current representative democracies are (including US). He would have loved the ideal of ultimate personal freedom but at the same time he would have loathed every control that governments have today over their citizens. There is no separation of state and religion in most of the western nations for example.

We are closer to world what Focault said but he is more recent scholar.

this seems like a very delusional take to me

> It argues that people should be permitted to say whatever they wanted, provided they obey the laws. that's exactly how it works

> Most recently the EU is considering a “ban conversion therapy.”

this has nothing to do with the opinions that are expressed in conversion therapy but with the insane practices - which actually try to enforce people to think like they believe is the "right" way to think about the world, which is far more restrictive than just letting people be themselves

> Really Europe (and other places) are using it as a way to weaken freedom of speech.

this is unfortunately true, too many extreme right wing politicians have been successful recently

> It’s a bit scary the Europe is leading the way on this.

it isn't, the US (though not just the US of course) famously collects data and searches through all of it if they need, and recently ICE had a hand full of incidents where they clearly used databases to profile people (just look at their use of AI cameras at protests)
