I always look at these posts of people writing about pit bulls out of a place of fear. And just shake my head. But the post I replied to talked about logic, and research. So let's logic.

Top Google search,Wikipedia "Pit bull is an umbrella term for several types of dog believed to have descended from bull and terriers.

"Pit bulls" are the most abundant dogs in the United states. The most common mutt is called a "Pit Bull". Everyone who is afraid of dogs these days think Pit Bulls. I remember when it used to be German Shepards. People afraid of dogs would say German Shepards are evil dogs bred to hunt people.

Don't be ruled by fear. Dogs are dogs. They are domesticated carnivores, and unknown dogs need to be treated with caution. You never know if they've been abused or have behavioral issues.
