Pit bulls have a long history as a working dog and regularly pass dog temperment tests better than some other breeds. Just being a pit bull doesn't make the dog a ticking time bomb or a killing machine.
The dogs shown in the pictures are good examples of their type and are doing good for society. Pit bulls also serve as certified therapy dogs and police dogs.
If it’s all the same to you, I’ll refrain from letting my child spend alone time with a muslim, a demoncrat, Larry Craig or a Pit Bull of your choice.
