The point is no dog should bite; and when a dog bite occurs its not the fault of the dog but the fault of the irresponsible owner. Should we ban everything irresponsible people use to injury people with? The fact remains the vast majority of pitbulls will never harm a person in their lives. Do you punish the responsible owners for the sins of the irrresponsible?
Pit bulls as wild animals? For more than a century pit bulls have been known as nanny dogs for their tolerence of children. This historical precedent refutes your statement.
Why are you so insistent on punishing people who breed and own pitbulls responsibly with the people who abuse these animals. Do you really think that banning these dogs will stop them from being used inappropriatly? Even if you erraticated every pitbull on earth do you really think these people will stop taking dogs and making them mean?
A breed ban is an easy feel good attempt to try and fix a problem that has nothing to do with the dogs themselves. It has everything to do with bad owners. It accomplishes nothing but killing dogs that have and will never do anything wrong.
