Would you say a pitbull is bad or the dog owner?

Pitbulls have such a bad rap, and so many are in shelters. Where I live there is no euthanization...thank god, but lots of pitbulls. I'm I the only one annoyed to hear how they are so mentally retarded it makes them a killing machine? I'll agree they are super strong, but if raised from a puppy by a good owner they'd have a good chance just like the rest. I've even seen pitbulls raised from bad homes transformed and became complete safe family dogs. Would you blame the owners?
