Often dogs are trained to fight and attack. Pitbulls have a bad reputation rooted in bad human behavior; it's not the breed's fault. The behavior of a few Pitbulls doesn't mean that the breed is inherently vicious. Instead it means that their humans are assholes. I've personally met many Pitbulls who were just big mushpots of love.
I've been shot at, had people try to stab me, seen and watched death multiple times, temporarily lived in one of the most hostile places on the face of the earth, but my heart melts at the soft sincere eyes of a Golden.
