Like Ish said, no one is ever going to change any minds. I am against all breed bans. In the 40s and 50s, the "dangerous" breeds were German Sheperds, Cane Corso, Doberman Pinschers, and Akitas. Why? because American servicemen from WW2 learned a deep fear of these breeds from the Axis armed forces.
In the 70s and 80s it was Rottweilers, thank to Stephen King's Cujo.
Pit bulls are regarded as dangers because of a sensationalist article from Sports Illustrated on dog-fighting. Yes, there are a lot of terrible people who got pit bulls because of a falsely earned reputation as a fighting breed. There is some degree of nature involved in their temperament. There is no denying that they have the highest bite force per body weight. But you cannot ban dog breeds because of your own fears and prejudices. Statistics on dog-bites which do not factor in owner behavior and lifestyles as irrelevant to breed behaviors as so-called "observational data." You want to know which breeds have attacked my dogs, unprovoked? A standard poodle, two chihuahuas, and a shih tzu. All four owners were inexperienced and did not know how to train and socialize their animals properly. Would you like to know what the fierce pit bulls did in response to be attacked? Nothing. they ignored the three small dogs, and just stood off from the standard poodle while I held it back. What have they killed? Rabbits, squirrels, and flies. A dog is still a dog.
I recently had neighbors with two Belgian Malinoises and a German Shepherd. All three were trained attack dogs, I watched them doing bite work with a cop in a protective suit. Them and my dogs loved each other. Running up and down the fenceline, play-bowing to each other, no problems. They would even sit down next to the fence and chill with me when I worked on the hedgeline shrubs. However, when other poorly trained dogs from the neighborhood got free and approached their yard, they would do a complete behavioral 180.
My point is you cannot blame breeds. I find it frankly immoral. You may have to put down a dangerous dog, but the owner should face stiffer penalties than are in the laws now.
