1) Start a letter writing campaign to the CDC calling them out on the problems with the study and their treatment of male victims: http://wwwn.cdc.gov/dcs/Requestform.aspx

If that doesn't work,

2) Start a petition demanding the CDC issue a public statement explaining themselves, improve their data collection methods and provide full and equal recognition of male victims.

A Whitehouse.org petition might be good (although the 100,000/30 day signature threshold is a bit insane). The Whitehouse just launched their "It's On Us" campaign against sexual assault, so now would be a great time to shame them into acknowledging male victims.
