You're obviously pretty set in your ways. Anyways, I didn't say they were physiologically different, but they do have much stronger jaws than most other kinds of dogs for their size. Just look at the muscles on their head and neck. You can swing a pit bull on a rope in crazy circles through the air and the little bastards will never let go. They also have quite short jaws meaning you can't get much leverage to pry their mouths open should they bite you. If banning pit bulls is the way to stop bad people from owning them and training them to attack, I think its great. Just like banning guns hugely reduces gun crime. Frankly, I don't care about good people who are pissed that they don't get to have guns anymore. Anyways, since ten million people can't settle this I doubt we can.
