Hate speech is not a thing. It is a falsity that dumb people accept as a form of censorship when they don't like something. There are simply things you don't want to hear and things you do. Threats right? Nope.
It is true that "hate speech laws" are limits on free speech. It is perfectly reasonable to consider any limitation on free speech to be unethical, but pretending that "hate speech" is not well defined is willful ignorance. No country has absolute protection of absolute free speech.
This seems to blur the lines between "hate speech is a thing" and "hate speech should be banned." They are fundamentally different questions, and conflating them invites the normative fallacy.
Surprised you're not being heavily downvoted already. (I don't agree with that, just surprised.)
I do however think extreme hate speech is a real thing, it's just misapplied to the point where anything anyone disagrees with is labeled hate speech.
Because at the end of the day, all negativity is based on hate, right? If you can't say something nice, don't say anything at all (which is a nice convenient bromide for eliminating real critical thought.)
