The dogs being aggressive, and being forced to kill each other are two totally different things, sorry. No, dog fighting isn't on par with hunting, sorry. Yes, hunters kill animals for sport but, especially in the case of deer, if THEY don't eat the meat, the meat is donated to the less fortunate.
The only thing benefited by dog fighting is vick's already fat wallet. vick ftl. he's an untalented waste of $$ anyways, and he broke the law so, throw his ass away.

Oh, and just so you know, I love how it's a black vs white thing now.
