A lot of idiots use them as an accessory to go with their little hood persona. So yeah, pits definitely have worse dog owners than any other breed.
With that said, their bite force and the fact that they were bred to fight till the death makes them inherently more dangerous than any other dog. I have a pit mix and even though I have full confidence in him when I'm around I make sure he doesn't approach anybody else because I can understand why someone else would be intimidated. I also don't leave him unsupervised with our smaller dogs and wouldn't leave him with a small child of mine. People that have blind confidence in them are idiots. There's a story of two pits killing a 2 yr old and 6 month old despite 8 years of ownership with no prior incidents of aggression.
