I have to say, what Michael Vick did was awful. It's terrible to torture and kill a living thing. Any animal. He went to prison for it and lost millions upon millions of dollars in salary, promotions and endorsements.
He paid a heavy price.
At the same time though, our society is strange. During hunting season we allow people to take to the woods with guns and bows, and blow a deer's head off in front of it's family, or put an arrow through it's chest, allowing it to escape and suffer and die over the next week. There's all kinds of inhumane practices with the raising of cattle, pigs, chickens etc. that are horrific.
I struggle seeing the difference between attacking a deer, and what Michael Vick did with the killing of dogs. Because it was a dog, all of the sudden everyone loses their minds.
I'm not a vegetarian by any stretch of the imagination. But I don't see how we can punish Michael Vick for fighting and killing dogs on one hand, and promote the wholesale slaughter of other animals in brutal, brutal ways on the other.
I say let Vick play. And if someone on the field wants to take aim at him for his past, I'm sure he can handle himself at 6' 215 lbs.
