You can tell a lot about a person by observing his dog, and many of the arseholes that own pit bulls aren't fit to raise guppies.
Insurance companies will not insure your house if you own certain dog breeds - pit bulls being one of them - or if they do, they will raise your rate considerably. Perhaps landlords should require renter's insurance, or is that government overreach?
I don't want to register my guns, why would I want to register my dog?
Who said anything about registration? You're liable for any damage caused by your dog, and you can insure yourself against that. Simple transfer of risk, like any insurance. I simply pointed out that you'll pay more for a pit, than you would for a poodle. Yes, pit bulls are the red corvette of the dog world
