How much more stupid and absurd can this "sport" be?

Imagine
"runner tripped by official for not staying in lane"
"f1 race leader crashed out by race director in pace car for infraction"
"swimmer held under water for using illegal technique"
"soccer referee fined for pretending to be injured"
except the above actually happened...

Do you think this is normal in this sport? You're absurd analogies have nothing in common here. They don't pose a threat to anyone, but a trained fighter can still be a threat even when they are knocked silly. Do you think the ref should just sit there and get beat up?

I have seen a few times where a KO'd fighter gets up and tries to keep fighting thinking the ref is the opponent, but I've never seen a ref choke out the fighter before though. Refs are trained to handle these situations, and usually defend themselves from the fighter until they come to their senses or the corner team get there. Choking the fighter out may have been a bit extreme, but he stopped the fighter without causing harm the fighter.
