I wasn't comparing fighting dogs to molesting children- just using an illustration of how "baggage" can affect your franchise. If I were the NFL commissioner I'd kiss him goodbye. That's a direct response to the OP.
As to what Vick did and condoned- it's not for me. I know people who fight chickens. In all other respects they are good people but they do not see the roosters as anything other than base animals. I suspect that these people and people like Vick don't see the dogs any differently. I don't know how you can reform a person like that any more than you can reform an alcoholic or child molester. All you can do is keep them from repeating the behavior. (And that is not responsive to the OP).
