Anything in excess needs to be controlled/ eliminated. Even the rats, cockroaches and insects cannot defend themselves. So what do you do... Do you let them live.
Also if your child was mauled to death by a set of stray dogs, would you still keep the same rational approach.
Keep the pet dogs under leash. And the others need to be eliminated. All this talk is only by the rich elite bored housewives who have nothing better to do.
