Dude, they already have them in the UK. And Canada. Certain ideas and expressions of those ideas are outlawed based on how they spread: "misinformation" and "hate".
Misinformation (ie, not knowing what you're talking about, but speculating and trying on theories), or being in the unknown, is the foundation of frontier science, which is basically the invention of ignorance. So, you're no longer allowed to think, and if you can't think, you have to be told what the truth is...So...religion I guess?
Hate (ie, a wide spectrum of behaviors that is easy to allege but challenging to objectively verify and often deployed without nuance, self-awareness or impartiality) can just be subjective confirmation of existing biases. Hate could just be I don't like this person, then the accuser is like, "That's hate!", but then it's like, "Isn't it hate to accuse of that? Aren't people allowed their preferences?"
These dual problems of misinfo and hate (the new heresy and blasphemy, I suppose, administrative and legalistic tools which have been deployed in the past in the service of a ruling class to suppress or control a subjugated class), are exacerbated by the pseudo-collectivist elevation of one's "group identity" to a place of primacy, where the state seems to not only suggest that group identity is more important than individual identity, but it seeks to take responsibility for the interactions at group identity level, thereby amplifying the sense of victimhood, and lack of personal responsibility, that already underpins the psychological vulnerabilities that compels people into the larger cultural conflict traps already in play.
Anyway, that's my sort of literary theory, cultrual crit attempt to describe it, hahaha! :)
