As the buzz shows, the people like Manny Ramirez. Many of us aren't concerned about whether he took steroids or not. I look at it in the same way as athletes who have incredible surgeries to get or remain viable in their sport. It is artificial enhancement in a similar way.
There should be full disclosure, and then let the public decide whether a person has gone too far. Less ticket sales, t.v. ratings, boycotts, etc. will tell the story.
I'm not saying that there shouldn't ever be rules and laws against things like steroids, but that we should try to focus our outrage where it can be most productive.
