But you're wrong. It is accurate.
"Forbidden terms" is, indeed, a level of censorship. And this is exactly the type of thing that is getting people laid off and fired from federal work at this very moment.
You can argue that "it doesn't rise to the same level" as other countries - but that is dependent on your perspective and personal opinion, as well as the pre-existing conditions prior to this censorship change. It's all relative, and there is no concrete comparison between what we are seeing in the US vs other countries.
One other mistake you made.
ICE is well known for detaining (and worse) US citizens. As they are known for detaining (and worse) non-criminal aliens.
Your claim that ICE is only policing "criminal aliens" is 100% inaccurate.
