I don't know if speech should be regulated (I don't think so, e.g. calling out a public servant's racism is illegal in France) but a specific form of so-called "hate speech" is the only form that an agonistic perspective on communications and information deprived of cognitive resources (because the marketing competences that make capitalistic social media successful are used to typify both the public and the people who've signed their TOS and target... woopsie, marginalized teenagers) can take, so I'm writing that down in my list of bullshit excuses to control our interactions.
