It's "thoughtcrime" and "censorship" when they do it. It's "stopping disinformation" and "protecting democracy" when we do it.

Oh please. If a known bad actor is trying to influence your polity, the best solution is to block them.

This does not mean people should not also be educated. That critical thinking is also what leads me to the conclusion this should be blocked.

Believe it or not, removal of content is mandated on the basis of laws that have been passed by the majority of representatives elected by the people. For example, it is a crime in Germany to publicly glorify wars of aggression and use Nazi symbols or deny the Holocaust. It's also a crime to publish child abuse material.

On a side note, setting up a website deliberately designed to circumvent such laws will itself likely violate the law and might lead to criminal prosecution. While the US government will certainly be protected by diplomatic immunity, other people involved probably won't be protected.
