My qualms with your ridiculous claim have nothing to do with pitt bulls. Simply assuming that growers are somehow predisposed to one single, shared tendency is ridiculous. Other than the fact that we grow, we are so diverse that not one blanket statement can define a majority of us. Do you not see this? You made a ridiculous assumption, that's all.
I love dogs. I have three. They're not pitt bulls (whatever the fuck that means, anyway - at least refer to a purebred by breed, not by some connotative slang), but I have nothing against them. You, however, are buying into the stereotype accompanying many pitt bull owners - we're more intelligent than that.
