I’m fine with the government shutting down anti-democratic movements. I’m not fine with anti-democratic governments shutting down legitimate discussion that looks bad on them, or serving a foreign power. These are not the same thing.
The reason we would usually go for the fullest amount of protection for speech was precisely because most of those issues are not simply a matter of "these people are democratic and those aren't".
This is true, but your framing of it as something that could be stopped if… something? is absurd
Hmm, now where have I heard that recently?
The irony is apparently lost on them.
