Irresponsible owners make ANY dog a menace to society, not just Pitts. If Pitts have been raised to fight and attack, they shouldn't be around society.
It is not their fault. Every large HP breed has had its turn in the shit bowl. German Shepards, Dobermans, Chows and now Pitts. The dog that is working up the ranks in nastiness is far surpassing the Pitt, the Rottweiler.
Blame the owners. I agree, if the dog is acting irresponsibly, they are the ones to blame. Irresponsibility and hatred are not inherent gender traits, they are taught, just as they are with children.
Violence and hatred and a little media exposure will get you noticed everywhere.
