Trisher, you are automatically assuming that those of us who think it is wrong to slap and punch a horse would condone boxing. There is no comparison whatsoever between someone being deliberately cruel to an animal and two consenting adults choosing to compete in a boxing ring. And you really wouldn't care what teachers get up to in their own time - even if it happened to something which was technically legal, but morally or ethically questionable?
I said some people Blondiescot those people have posted on this thread, there's nothing automatic about it.
As I said you are entirely welcome to think slapping a horse is wrong I happen to think punching another human being in the face purely for entertainement and profit is wrong. But I wouldn't regard either as making anyone unsuitable to teach.
Lots of things are morally unacceptable- like our PM. Morals are not fixed they vary with culture, background, social status and many other things. I've known teachers who were Creationists providing they kept their beliefs out of the classroom it didn't matter.
