Z - sorry to get preachy...Sarcasm is often lost on the internet, and there are plenty of people out there who would be serious, and proud to have a mean dog.
I don't own a pit bull and never have, and I defend the breed too. They are the breed of choice for thugs, so they get a bad reputation (combined with the amount of damage they can do with those muscular jaws). In the past dobies, rotties, etc have all had the same stigma. News outlets over report pit bite incidents and under report others.
Unrelated but I was at a festival the other day and a teenage girl was selling pit bull puppies (she said only to families) and they were just about the cutest thing I had ever seen....maybe a shade over eight weeks and all smushy face and round bellies. Ohmygodcuteness.
