I have 3 amazing pit bulls and I absolutely love them. Never have they ever attacked my or hurt me. The only bad thing they do is have nasty breath. I hope and dream the one day people will understand how mistreated they are. The biggest mistake I made was not adopting one sooner.
Are some pit bulls violent? Yes. And mostly this is due to their reputation as vicious, so they are selected by bad owners who encourage them to be that way. But even if a few are naturally bad, that doesn't mean they are a bad breed. Do you feel scared to go near any human after you hear about a murder done by one? Obviously you don't. Because it would be foolish!
