You are relying on news reports that we know have changed over time to report only certain breeds. And news reports are not the same as properly collected data from hospitals, police reports, and vets. We know the news reports are not telling the whole story, because I personally know of dog bites by other breeds that are not reported at all in the news. Just extrapolate that, and you have a major problem.

This is the second time you have "quit reading" before examining the facts. That's the equivalent of sticking your fingers in your ears and singing, "La la la, I can't hear you."
