There's nothing Anglo-Saxon about it. Similar things are appearing all over the western world. And they are absolutely being brought up forwardly.
For example, German ministers can't stop talking about banning one of their most popular political parties outright and they have the powers to do so. They also have announced plans to introduce laws that criminalize "mocking the state", including the weaponization of every aspect of the government against citizens that disagree with them, for example by revoking their local business licenses, implementing exit visa (banning people from leaving) and "depriving them of their income". This also in cases where people haven't actually done anything but are merely influential [1]:
Interior Minister Nancy Faeser (SPD): "We are coming up against legal limits. At present, financial investigations are limited to incitement to hatred and violence. That is not enough. I therefore want to amend the law to ensure that the potential threat is taken into account. This involves other factors such as potential for action and social influence."
Germany is hardly alone. Ireland is also introducing a draconian hate speech law. [2] The EU is investigating one of its own MEPs for hate speech after he said he thought EU policy on asylum seekers was intended to attract more migration [3] (i.e. they disagree that it's OK for politicians to express opinions on government policy). In Finland the former minister of the interior was prosecuted for her tweets [4]. She was acquitted and then the government appealed to try and get her again.
The reason you think it's specific to the Anglo-Saxon world is just that those stories affect a lot of English speaking people and this is an English speaking website. Also, negative stories about the EU often get flagged here, and of course in many parts of the world like China such laws already exist for a long time.
