Louis Marinelli, the former Internet strategist for the National Organization for Marriage (NOM), is becoming a gay marriage advocate.

Marinelli's defection from the group last week was met with skepticism from the group's president.

While acknowledging that Marinelli was paid to help “expand our Internet reach,” Brian Brown denied Marinelli's claim that he was the mastermind behind the group's Summer for Marriage Tour 2010, a nationwide bus tour to rally opposition to gay marriage.

“Louis Marinelli worked in a volunteer capacity as a bus driver during our summer marriage tour,” Brown said.

But the mastermind-volunteer did control NOM's official Facebook page, which he shuttered, throwing off the lights on more than 219,000 fans.

In a even more surprising move, Marinelli is using his social media experience against NOM.

At his new Facebook page, Marinelli on Sunday posted a poll asking people how he can “best serve the cause of marriage equality.”

Over 40 percent of respondents say he should “Expose NOM's agenda.”

In an interview with gay blog Towleroad.com, Marinelli added that he's prepared to make himself “available to whatever organization needs my help in any way that they need it to do what I can to a) reverse some of the things I've done in the past and to b) help progress to help ensure that there is the freedom to marry in the future.”
