Like I said, they're perfect for dog fighting, so dog fighters choose them. Dog fighters train them to kill other dogs. They also often train them to be aggressive to anyone but the owner. That's why they top the charts. Same reason semi-auto pistols are the most likely guns to be used in a crime. They're perfect for the task. As for breeding aggressive behavior, pitbulls were bred to be aggressive toward small game, and for baiting dangerous animals like bears and bulls, just like the English and American bulldogs. Similarly the Rhodesian Ridgeback was bred to hunt lions and guard diamond mines. You don't want to run into a Ridgeback that's been trained to be aggressive toward people. Overall point is, make pitbulls extinct, and niggers will start fighting some other breed, and it will become the new deadliest dog. And on and on.
