I’ve never heard anyone advocate that you can train the basic instinct of a dog out of it like they do for pits.
Show me how to train a herding instinct out of a Border Collie, a retrieving/love of water instinct out of Labs, the rat killing instinct out of Terriers, or a digging instinct out of Dachshunds.
Pits are bred for fighting and killing. Same kind of instinctive behavior as others that can’t have it trained out of them.
Some people are immune to facts.
Your point is spot on..
