Oh Devo, I guess facts don't mean much when you got anecdotes.
Well if we want to speak "facts", human fatalities caused by dogs in the US in 2014 were 32 for an estimated 77m dog population and that's apparently a fairly normal number in line with previous years. That's barely above the number killed by lightning. Fatal dog bites represent 0.00001% of dog bites (according to the CDC study). That doesn't mean that we should shrug this problem under the rug, but just that in proper context it's a very minor problem in the grand scheme of things despite the common poor ownership and so called dangerous breeds.
Yeah you can argue that what's important is the number of bites requiring medical attention or something. I'm not saying it's an open and shut case. As I said, enforcing leash laws that already exist almost everywhere should be a good thing. I won't object to regulating access to certain breeds although I don't think it is efficient. Pit bulls should be recognized as a breed in the US so that breeding regulations are applied. That could curb the number of unbalanced and poorly socialized dogs.
Comparing it to gun apologists is ridiculous because it grossly overstates the dangerouness of dogs. Dogs are not weapons in fact dogs are incredibly safe judging by the number of fatalities.
The entire breed shouldn't be wiped out. That's not nice at all. But does a family with children really need a pit?
Who really needs anything, at that point ? Who needs skiing or doing anything with an horse, or going for a swim ?
The thing is most people own mutts as well, so right off the bat it's never that easy. A lot of families may own dogs that are half from a so called dangerous breed without knowning it. Also consider that families may choose a dog for guarding (which may be misguided or inefficient but heh).
