Because one child was left to the dogs by her parents, you blame the dogs and want to wipe out the breed? No.
You are not making sense. You say that only biting pits should be put down, but then you say you want to exterminate the breed, whether the dogs are deadly or not.
Confused much?
Your broad brush leftist tactic will be your undoing here. You just went from a pretty okay guy to an idiot for sucking down that leftist Kool-aid, IMO.
The behavior of dogs is determined by their upbringing and handling. The owners of vicious dogs are the ones whom we should stop from breeding. </sarc>
It is not the dogs' fault. You have this one very wrong.
To paraphrase OISA, "Oh I don't mind people having guns, but lets make sure no more are ever manufactured, okay?"
