These people think that minimum wage "fact checkers" who delete posts that don't agree with their handbook are "freedom", not "censorship". So they think they have principles.

This is an absolutely unhinged take. The US doesn't allow more than 25% foreign ownership of broadcast media. That's not some "free speech" violation. If a foreigner wants to say something, they have many ways to do it. But they don't have those privileged ways.

All principles have exceptions.

Just like how all normal people love free speech until it comes to CP and death threats (which of course should be banned).

Which principles are we talking about?

If everyone under the age of 30 was using an app run by Nazi Germany would you be okay with that?

Propaganda is a weapon and no principle says that you should let an enemy army into your country.
