1. Respond to whole posts, not partial ones. It's obvious you're avoiding parts that blow up your argument.
2. That's "reported" bites. Pitbulls are an extremely popular breed and they're usually big dogs so they have damaging bites. Small dogs bite far more but they don't do as much damage, so it's not reported.
3. "Pitbull" isn't even a real, singular, breed. The American Pitbull Terrier, Stafordshire Terrier, and a couple other bully breeds are usually all thrown into the "pitbull" label and the "bully breed" label, so really you're reporting on bites for 4 or 5 different breeds as one entity. Of course there will be more.
Stop worried about pitbulls and start worrying about normal human social interaction
