My take:
Since it's impossible to accurately define who did what during the steroid era, we swallow hard and let them in. There is no fair method of admission and exclusion, and the writers shouldn't be playing judge and jury on this.
Both MLB and the writers chose to look the other way during the steroid era. The playing field was the playing field during this era, the same as it was in the deadball era, segregation era, etc... It's not a pretty slice of history, but it happened. The players who played were major league baseball players, and should be part of the major league baseball hall of fame. The historical numbers are already skewed, the records are public, and exclusion from the HOF doesn't change that. It's up to the fans to say that "Bonds hit more homers but I think we all know why". Sanctimonious writers like Tom Verducci, George King, Howard Bryant, Lavelle Neal (to name a few) turn all the baseball awards into a popularity contest and a soapbox and diminish their relevancy, and keeping Bonds out doesn't undo his accomplishments, just like Pete Rose is still the hit king (followed by another rather loathsome character who resides in the Hall, not in the writer's trashed vote wastebasket).
The Hall of Fame's Motto is: "Preserving History, Honoring Excellence, Connecting Generations." Total failure on all points with this vote. I think that in addition to opening the doors to suspected and known users, they open a wing for the Mitchell report and detail the history of this era and how it unfolded. Come clean and move forward.
Excellence, as voted by the BBWAA:
The oddest Hall of Fame votes in history
