Yes, Kaylin Hamilton recently wrote an article about the woman boxer you allude to, focusing on how the French legal system is investigating several public figures who defamed her.

The number of thoughtless "this is against free speech!" comments Kaylin received demonstrates a serious lack of understanding of free-speech principles.

Obviously, France has a different legal system than the United States, but in the broad strokes, prohibition of defamation (and the prohibition of incitement to violence) are common to both systems.

It's unfortunate that few people think about or understand why free speech has certain traditional legal limitations.
