I was actually having a very similar thought the other day, though I didn't call it a boner and it was related to something different. It was when people were crying over Michael Vick being a Pro Bowl team captain.
I love dogs. I would never support dog fighting. But come on, the man has paid his dues and apologized and not repeated the same mistake. Move on and recognize that some (not all) people are capable of change and repentance and when they are, support that. We need more of that.
