If it is for sport (as it is for them) yes. I don't agree with hunting. However, unlike dog fighting, it is legal. So while I disagree with both, as long as people abide by the laws set forth as many hunters do, I am ok with it even if I don't like it.
However, Vick broke the law, and now he has to live with the consequences of his actions (whether is his time in jail, loss of fans, etc.).
I don't know why you're defending him. He has been proven guilty of the crimes he was alledged to have committed in a court of law. Therefore, there really isn't much defense you could have for him.
