Baltimore Ravens center Matt Birk believes Maryland gay couples already receive benefits similar to marriage.

The 36-year-old Birk made his comments in a video for the Maryland Marriage Alliance, the primary group working to defeat at the polls this November a gay marriage law approved by lawmakers.

In the 30-second ad, Birk says marriage is the foundation of society and children.

“Marriage is more than what adults want for themselves. It is also about the next generation. Marriage is and should remain between a man and a woman,” Birk says.

“Gay and lesbian couples already receive benefits in Maryland, like hospital visitation, state health benefits, and tax breaks. We don't need to redefine marriage,” he adds. (The video is embedded on this page. Visit our video library for more videos.)

Birk also recorded a video for the Minnesota Catholic Conference in support of Minnesota's proposed gay marriage ban. In the video, he says he supports the amendment because marriage equality would hurt children.

Teammate Brendon Ayanbadejo, a proponent of gay nuptials, tweeted support for Birk, saying that he has a right to his opinion.

“Matt Birk is an amazing father, teammate, man! Even if he & I disagree on marriage equality we agree on 95% of other issue,” he said. “I don't think he's homophobic at all.”
