Why in the hell, AV is not convinced by these facts?
The beast (whose "voice" is the AV) is not going to be convinced of anything ever. It has but one agenda. Discussing things with the beast is about as productive as discussing them with a horse. It's not going to work.
The only thing that works with the beast (and a horse) is consistency. Consistently stick to your plan and the beast becomes so weak that it's occasional acting out is nothing more than a passing annoyance.
A horse that is given even a tiny bit of it's own way will quickly become unmanageable, but one that is broken and trained well will always faithfully submit. It's an animal after all and we expect that from it. Similar principles apply when becoming a beast whisperer.
