Why do people but pits, and do not know enough about the breed?

In the last to weeks I’ve had two pits gave to me because the owners bought them and no longer could keep them. One I kept for myself, and the other a 10 month old red male I gave to a friend.The guy who had the 10 month was just going to turn him loose, to run about. My daughter and son in law who has a pit themselfs picked him up and gave him to me.What really gets me mad is the dumb people out there who want to blame so much on these breeds, when it is because people dont do their homework.All it take is read, study, and love these big babies.
