Let me a bit more precise. I'm not claiming that the US actually always follows its own standards, or that there aren't authoritarian oversteps of power -- there are.

I'm just saying that the American definition of freedom of speech (whether the authorities follow it in practice or not) is unusually expansive. Edge cases like hate speech against particular ethnic groups, public insults, open support for terrorist organizations, etc. are much more likely to be legally protected in the US than in other countries, even including other liberal democracies.

That used to be the case, and I agree in principle. With the current administration, however, this is no longer true. Freedom of speech stops being free speech if the government detains people and revokes visas for having a certain opinion, tries to dictate the curriculum at universities, forces trans people to their birth gender, acts against lawyers with the wrong clients, excludes unwanted media from press conferences or sues them altogether… this list goes on for a while.

Donald Trump is a danger to the fundamental rights granted by the constitution, and the republicans are assisting him in tearing it down.
