If I remember corrrectly, Mr. Vick WAS terminated, then after he paid his debt to society, NFL thoroughly examined his life and determined that he was worthy of receiving a second chance. It is clearly evident that his life on and of of the field have demonstrated that their faith in Mr. Vick were well placed.
I do not know what you do for a living or the company you work for. If Mr. Vick had been working in a bank, or in a field dealing with large amounts of cash and he had been convicted of theft or monitray fraud then I would agree, Mr. Vick's felony conviction would probably disqulify him from working in that field again. However, that is not the case. Mr. Vick throws a football for a living and he is very good at it. His felony conviction has no bearing on what he does or on his ability to do it. As a matter of fact, Mr. Vick's demonstrated faith in Christ and his restoration to a productive memeber of society make him a great testimoy to the forgiveness of God and His ability to restore broken men and women.
Those were just rhetorical questions based on the long-discarded notions of community standards and fair play. I already know the answer: celebrities are treated to thier own rules and privileges that we lesser men must not question. "You wouldn't want to deprive the world of a talented player, would you?" "You want to give young African-American someone to look up to, don't you?" Etc, ad nauseum. Or as someone else implied, "you wouldn't like Mr. Vick if you took away his football. He might get very angry and do more Bad Things!"
Also, please don't conflate employers with the Church. The Church, and individual Christians, are obliged to forgive. Employers (and all those in secular authority) are not under any scriptural compulsion to forgive and forget. They are charged to protect thier own interests, and by extension the common interest, by all legal means. (Romans 13, et al)
