Then they're guilty of the same type of hysteria that you've been arguing against in this thread. I'd like to see how one goes hunting with one's dog on a leash.
In any case, you're ignoring the main issue which is different breeds have different behavioral traits, some of which are aggressive in character, and which can only be mitigated by training. Since that's true, then some dogs are inherently more dangerous than others. Given the characteristics that the American Pit Bull Terrier FAQ ascribes to pit bulls, it follows that they are a more dangerous breed than most others. So are mastifs, rottweilers, ... This doesn't mean that people shouldn't own them, or that they don't make good dogs under the appropriate circumstances.
I will add that there are a number pit bulls that come to our dog park. When certain of them show up, everyone leaves. Why? Because these specific dogs have demonstrated their aggressiveness. Sure the owners are idiots. But a cocker spanial in the hands of a poor dog owner is less dangerous than a pit bull owned by a similar person, maybe not always, but certainly on average.
