I've met pitbulls whom I found quite nice and pitbulls I wouldn't go near. In both cases, my reaction was based on behavior, not breed. Having had one knock over an older, small dog of mine repeatedly as we walked our regular walk route a couple of years ago (after slamming into me so hard that I ended up with a slightly injured wrist on his way to get to my dog), I am definitely more cautious around them when with my leashed twenty pound dog. To be perfectly fair, the same week, I was walking the exact same small dog and another pit bull came out of nowhere, just as the first hand, and I put myself between that dog and my dog and told it, in no uncertain terms, to stay away from us, and it immediately hit the ground and looked as if it might cry. I apologized and it wagged its tail and looked relieved, but it did stay back and away from us when I insisted upon it. Even if it was a friendly dog, the size differential worried me, as its idea of play could have become too much for my smaller older dog, and for me, as I was recovering from shoulder surgery and had only recently gotten out of my sling.
I think the problem for pitbulls is complex. Part of it is that there are simply too many of them because they are, at the moment, a popular and profitable breed, leading to too many of them being poorly bred. Their numbers are far greater than the number of appropriate homes/owners available for them. The controversy surrounding them also leads to the two worst types of owners they could possibly have getting their hands on them: those who want them to portray a "tough" image and/or fight them and those who want to prove how unfair their reputation is but who are completely unprepared and/or ill-equipped to handle a big, strong dog with a prey drive appropriately. I was in a class with a couple who fit into the last category and their Angel (the dog's name--I'm not being sarcastic) may have been the "good dog" they kept describing her as at home, but she was not a good candidate for therapy dog training because she was definitely dog reactive. She went after everything from a toy poodle to a sizable labradoodle for no other reason than that she apparently felt they were uncomfortably close to her. They weren't any closer to her than would be normal in a training class, but it was too much for her, and her owners couldn't handle her when she got aggressive because one had a bad knee and the other a bad hip. Why they thought a big, strong, young dog was a good fit for their situation, I have no idea, and it also irked me that they kept going on about how people were so quick to misjudge pitbull behavior, when their dog kept reinforcing all the stereotypes they wanted to destroy because they couldn't handle her and didn't understand--or want to admit--that she just wasn't going to be able to pass the TDI test, as she wanted nothing to do with other dogs being within ten feet of her, and the more they kept denying that, the more miserable and reactive she was going to be. Maybe with a lot of training with an appropriate owner, she would have gotten better, but as it was, it wasn't going to work, and all they were doing was upsetting their dog and everyone else in the class, who, quite logically, didn't want their dogs near that pitbull because of its behavior, not its breed. If it had been a snarling, snapping cocker spaniel who went after other dogs, I wouldn't have wanted my dog near it either.
Honestly, for everyone's sake, including the various breeds that make up the group commonly referred to as pitbulls, I wish their popularity would start fading because if it did, dogs and people would probably be better off as then there would be fewer poorly bred pitties out there and fewer dogs in the wrong hands/homes.
