I agree with most of that, believe it or not. Except for the bolded part. I'm not convinced there's any solid, imperical evidence that supports the pitbull is all that more dangerous than a husky, a dobberman, a german shepherd, a bull terrier, a Gull Dong, a rott wieller, or a Caucasian Ovcharka.
Take a look at the wikipedia article. At first glance, Pitbulls are a menace. They are implicated for 42-45% of attacks. This section highlights it quite well:
That seems downright damning. But then look at a lack of mention if the dogs were well treated, kept up on shots, trained to fight or be menacing. No mention of the social or economic upbringing. No mention of if the dog felt threatened. And even if it is mentioned, the person reporting it was the one that got bit, or knows the one who got bit. Doesn't that seem a little convenient?
Now look at the "Other Studies" section:
So, when Pitbulls aren't common in the area, it accounts for only 4% of fatalities.
True, a citation is needed, but once identified as bad owners, and having to own up to that, Calgary hit a 25 year low of bites.
This seems to backup the statement above about the dogs upbringing/training/environment. If you're a bad owner, you have a bad dog. A bad dog can be any breed, and a dangerous dog can be just about anything over 20 lbs. Kinda like this site shows:

If we're gonna ban this breed, perhaps we should just expand that out and say any dog over 20 lbs is banned. Once you get rid of the pit bulls, there's just gonna be a new bad boy on the block with something else.
Just like with guns, we need hold owners responsible.
