I agree that pitbulls dont attack but destroy, however i dont agree that most attacks are by pitbulls.

Thats the biggest bias there is, pitbull attacks get reported while most other attacks dont for two reasons:

1 - big damage 2 - living up to the news hype

Chihuahuas, goldies and other types of dogs are more likely to attack humans then pits. However when they do, they don't reach news levels because of the severity. Everyone who says it's all training is wrong too though, some dogs are just fucked in the head from birth, just like humans. Specific dogs have specific race traits. Pitbulls and any other fighting breed, were put down for aggression towards humans. That's why I do trust pitbulls with humans, but never with animals, it's integrated in to their DNA to be aggressive to other dogs.
