LOL. I don't think you're a moron, but I disagree. They are 3 seperate breeds. I wouldn't refer to an Amstaff or a Staffie as a pit, just the APBT.
In common everyday practice, you are correct.If you answer "I have a Pit Bull" that could mean you have one of the 3 breeds. Who agrees with me, and who thinks i'm a moron?
