hate speech in the EU is "incitement to violence or hatred based on race, colour, religion, descent or national or ethnic origin"[0].
You should be able to see criticism is fine, while calling people "stupid monkeys" is not.
But this isn't even about the EU's definition: Facebook & co have their own definition of hate speech, and they are not holding it up.
