hate itself is real - a word that has a negative connotation, but was never illegal in itself. You could always hate a person or a football club. That word was taken, rebranded to include among other things everything critical of government and made illegal. That's why hate speech is made up. What is called hate speech today was called a rant, "hot take", an insult or whatever just a couple of years ago. Today we literally have a law against "hate crime" - another doubleplusgood word. These things are not real, they're tools to oppress a critical population. Also note that even true things fall under those "crimes". It doesn't matter if what you say is true as long as it's "insulting" to someone.
