yeah, this is way simplified, but i think it's pretty accurate.


Yep- you're fairly accurate from what I've seen.
Some things I think you missed, though:

1. A lot of owners in the "thug" category aren't interested so much in dog
aggression, as in wanting a mean dog to intimidate *humans* with. Some of
them have deliberately bred for human aggression- including doing things
like crossing in Chows- some "train" to encourage it.
2. A lot of "pet bull" owners are convinced that the breed's fighting
history is myth or hyperbole, and/or believe that simply letting a Pit play
with other dogs is enough to prevent the dog ever showing dog-dog
aggression. "It's all in how you raise them" is their mantra, followed by
"S/he has never done THAT before!" when the dog starts going after other
dogs as it hits adolescence.

3. There's crossover between the types of owners. For a perfect example,
the whack-job that we had to call the cops on several times last summer. He
fits your first category, because he's very well versed in the history of
the breed, and displays most of the characteristics you list; let him get
talking to you, and he'll go on and on about the breed's history (I think
he's got at least one of the Stratton books memorized).
But he also fits category two, since he gets his jollies by taking his
large intact male Pit to parks where people let their dogs offlead. He
deliberately hangs near groups of dogs playing, lets other dogs approach,
then lets his dog attack them; he laughs when people protest, and smugly
tells them they can't touch him, legally, because his dog is leashed.
Not to mention that he boasts to women about his dog's sexual prowess, and
on one occasion unleashed the dog & encouraged it to try to mate* with a
spayed female. When the dog's owner protested, he said "You know your dog
wants it as much as mine does."

*Yes, the Pit actually attempted the act- the female was taken to the vet,
and had bruising and tears around the vaginal area.
