I learned long ago that there are people who are so ill informed that compromise is impossible. The only solution is to legislature around them. And that's why BSL will continue to win...because it is impossible to argue with stupid. The only winning move is to ignore them and legislate around them. Most of them live in trailers and don't vote anyway.
So all people who live in trailers are classless criminals? That's the kind of ignorant social casting that makes everyone involved look bad. I'm sure everyone is a perfect angel where you live, no crime, no pollution, nothing at all, then? I'd also like to add that 90% of trailer courts don't allow power breeds like boxers, pits, rotts, or german shepherds.
I've had personal experiences with pit bulls, good and bad, as well as many other breeds. And while some of it IS genetic, most of it is the owner's fault.
I've also owned a pit mix, the only issue that I had with her was that her previous owners didn't train her, or their toddler to stay off of the dog, and so the dog didn't like the baby. I had to try to completely retrain her to be a member of my family, and our pack (I had 3 other dogs). Like most terriers and terrier mixes, she was stubborn.
I think she ended up at a shelter though, because my ex took her with him when we broke up, and he couldn't control her. He'd kept encouraging her to "attack", and she scared a neighbor so bad she wouldn't get out of the car.
HOWEVER, when I had her in line, she was the friendliest lump of grins and snuggles you would've ever met.
It's not always Nature, more often than not, it's nurture.
Also, I agree with Fishfriend, those were bad parents for not teaching their child better. I have a toddler too, and if there was a hole in my fence, you'd best bet I'd find a way to patch it up, whether there were dogs on the other side or not. Also, my son doesn't play outside unattended, nor is he allowed to venture too far away from me, in our own yard or not, because you never know what could happen.
