poquas poquas:
They (pitbulls) are not "by nature" any more aggressive than any other dog.
Forgive me if I respectfully disagree. The dogs were specifically bred for their aggressive and tenacious natures. Like a fine racehorse, a good pit bull could earn thousands of dollars in the dogfighting 'pit' and the breed arose from devotion to the 'sport' of dogfighting.
Absent the perceived need for a dog capable of sheer brutality, the breed would not exist.
I'll not argue to ban them any more than I want to ban guns. But where it is reasonable to expect people to practice utmost safety with a gun as opposed to other types of tools, it is also reasonable to expect pit bull fanciers to adopt safety practices in line with the inherent dangers of their dogs.
