Enough A-Fraud

Alex Rodriguez took steroids. He hit lots of home runs. Why should I care? Honestly, I can't get my hackles up about this. Someone needs to explain to me how taking steroids to "unnaturally" improve your performance is any different from having Tommy John surgery, which "unnaturally" embeds a tendon from your foot or forearm into your elbow.  Should everyone who's had Tommy John surgery (or a repaired ACL for that matter) have an asterisk next to their name too?
