I think a lot of it has to do with image for a lot of people. A lot of rough, tough, wanna be macho guys want a "bad ***" dog. They're used for illegal fighting. So, there are a lot of back yard, idiotic breeders to cater to these shallow, insecure, creeps that couldn't care less about animals. Their narcissistic image needs something like this. So many of the dogs bred are bred without any concern for temperament, health or early socialization of the pups while still at the "breeder's." Then the creeps get their pup and further perpetuate the already lousy temperament by not socializing or training the pup and mistreating it in the misinformed opinion that that will make the dog "tough." I can only imagine the goings on. So those dogs get out and kill other dogs or bite and kill some human being and then the **** hit's the media fan. Nevermind the responsible breeders, responsible, loving pet owners who love the breed for the breed's correct temperament. It is ridiculous that breed ban enthusiasts and the media can't see this.
