You have basically backed up everything I have said. Your kids do not have to be afraid of MY dog (a pit bull) because MY dog will never attack. I am not asking YOU to be a dog expert because of my dog. But if you do own a large dog (any large breed), and you have small kids, you damn well better become a dog expert really fast.
And I agree with you that most people are idiots when it comes to dogs. I said that myself. I think that people should have to be licensed to own a dog...that's right, pass a test and everything. Because ANY DOG CAN ATTACK. My pit bull was attacked in NC at the dog park by a yellow lab. She would only stand next to her owner (possessive behavior) and when any dog got nearby, she bared her teeth. Mine got a little close, and she bit right through his upper lip. This was not a breed problem here...it was an owner problem. That owner never knew how to properly raise his dog, and it showed all too clearly to everyone else in the park. He was asked to leave by a woman there.
You are also correct that dirtbags are attracted to this breed because they are very powerful indeed. I do not deny that, that's one reason I like my dog so much. Denver and Aurora, CO (among other cities) have banned these breeds. But again, it is not the breeds that are the problem...it is the gangs. I work in Aurora, and drive through it every day. I see assholes walking their pits down the street, even though animal control told me i could not live in the city limits. That breed ban does not make these idiots obey - all it does is punish responsible dog owners like myself. The criminals will still do what they can. If we made guns illegal, criminals would still get them, too.
The crackdown needs to be on the owners and perpetrators of the illegal activity - not the dogs themselves. I am so tired of the DOGS being made out to be the criminals here...they are not the criminals. Yes if a dog attacks a child, it should be put down, no question. But the OWNER of that dog should be made to pay, too.
