We can't answer your statement that we are pro BSL breed/banning because we don't know what your initials stand for, but we can say that we have not ever suggested that any dog ought to be killed simply for being of a certain breed. What we do believe is that the breeding of certain breeds with certain characteristics ought to stop.
We believe that it is stone-age savagery to allow the breeding of fighting dogs, dogs that are deliberately bred to attack without provocation or warning, and to fight til the death, and which are deliberately designed to be so powerful that they are impossible to stop. Pit bulls are admitted, even by their greatest fans and defenders, to have high prey drives. Many pit bull owners, rescuers, and defenders, say that their pit bull is a pussy-cat, but then admit that they are not safe around other animals. Most pit bulls live unnatural lives of isolation because of this.
