MWM, my dad was exactly the same way about having the male dogs neutered. He had no problem with having the females spayed but absolutely refused to have the males neutered. A lot of men felt that way ... hits too close to home, I guess. In our case, if there was a female in heat anywhere in the neighborhood, our male dog would manage to get out of the yard so he could "get acquainted".
And I too love pit bulls. They're wonderful dogs in the right hands. But I agree that most people don't need to be breeding them. BSL (Breed Specific Legislation) is a sad fact of life in many places. And when selling or giving away those puppies, do you really know what those new owners intend to do with them? I wouldn't want that responsibility. Even in a small rural town like ours, every week there are at least one or two ads in the paper for pit bull or pit mix puppies. And I guarantee you that in a year or two, almost every one of those dogs will end up in the animal shelter where they will be euthanized. They don't adopt them out, they put them down almost as soon as they come in the door. People consider them a threat even if the dog hasn't shown any aggression at all. There is so much ignorance out there, but it IS out there and a lot more education is needed. And most people can't tell a real pit bull from a dozen other similar breeds so it affects lots of others too.
