This is dangerous stuff indeed. Society is increasingly turning away from the ideal of free discourse, putting "free speech" in mocking quotes. Politicians use "protecting the children" as an excuse for grabbing power.

The test of commitment to free speech is your willingness to recognize the rights of those whom you don't agree with and may even despise. Whether you call it "hate speech" or "grooming," if you make an exception for it, what you advocate is freedom for those who agree with you — and who doesn't advocate that?
