I oppose letting anyone define hate speech as a matter of principle, because even if I agree with the definition completely now, I may not continue to agree with the definition in the future. Look at what has been happening in the USA since the October 7 attack: a lot of people I had considered my political allies turned out to have beliefs I consider to be hateful, and meanwhile these people consider my own beliefs hateful. The solution is not to empower a single central authority to decide which sort of hate is allowed. It is (as it has always been) to maintain the principle of free speech.
