Yup, I can definitely see the family resemblance!
You may need to have a word with your nearest and dearest. Not saying you are lying. But...
One of the rescue groups I follow - Stray Rescue of St Louis - rescue and rehome loads of pitbulls, and they have nothing but praise for the breed. And many of the dogs they have rescued are absolute sweethearts.
Over here, pitties are banned, but the USA do appear to have a love affair with the breed. Regrettably there is much abuse of them - by owners trying to turn them into ferocious guard dogs, and by lowlifes who simply abuse animals for the sake of the abuse - but they also have a very strong following by ordinary people, who love them for their antics, friendly disposition, loyalty, etc.
SO...perhaps it really is worth taking a chance on the dog. Or else contact a pitty rescue (perhaps Stray Rescue) and ask for advice?
If I were a dog person - I love dogs, but cats are my passion. My avatar is of Felix and Bolt, the Huddersfield railway cats - I would certainly consider getting a pittie.
Keep us informed, please.
