>I find this abuse horrific and you should speak to a therapist if you think this is okay.

This is unintentionally hilarious. You're not arguing the moral point, you're using the same kind of reasoning that leads to gay conversion therapy. It roughly equates to: "that's not in accord with my social norms, therefore you need professional intervention."

(Perfunctory disclaimer that I don't support caning. I am not arguing for it, I am only pointing out problems with a statement against it.)
