Draft horses don't kill as many people as dogs maul.
Where is your proof for that? I actually know many more people who have had accidents with horses than have a dog attack them. Also.. it was an analogy between a draft horse and a miniature horse (i.e. a horse the size of a dog).. but the whole point was moving your logic about dogs to an analogy of something else.
they do have natural agressive instincts.
Yes, if a large dog bites you it has the potential to do more damage than if a small dog bites you, so you support the banning of all large dogs? Let's ban a bunch of other 'potential' dangers then. Horses, cars, guns, and how about the human race while we're at it? Where do you get that large dogs have natural aggressive instincts? If anything smaller dogs have more aggressive tendencies than large.
I read another page not long ago (and I'd search for it, but obviously the time and effort of digging all of this up is wasted), that the vast bulk of fatal attacks happen on the dog's own property, a big percentage by dogs who live their lives on the end of a chain with very little human contact. It's most often kids who were tormenting the dog, or owners jumping in to break up a dog fight and getting caught in the middle, or even someone trespassing, i.e. trying to break into the owner's home.
Finally, comparing a dog being aggressive to another dog to a person who abuses animals and then moves on to people is just completely ridiculous. A dog who is territorial to a strange dog has ZERO in common with a person who abuses animals for kicks. You are really reaching now. I think I'm done though as it's obvious you're going to continue to cling to your apallingly fallacious reasoning no matter what proof is offered to the contrary. You really seem to know very little about the true nature of dogs, nor do you seem interested in learning.
edit: The bite statistics did not include dogs that were part of the police, just like a shooting crime statistic would not include police officers shooting someone who drew a gun on them.
