Minnesota Vikings punter Chris Kluwe on Friday debated the statements of gay marriage foes.

Kluwe has become an outspoken supporter of marriage equality and an ardent opponent of a proposed amendment to the Minnesota Constitution defining marriage as a heterosexual union.

His advocacy drew the ire of Minnesota State Rep. Mary Franson, a Republican who labeled the player an opponent of traditional values.

In response, Kluwe offered a debate on the issue.

Neither Franson nor any other opponent accepted the invite, leaving Kluwe with an empty chair.

For his debate at the Brave New Workshop in Minneapolis, Kluwe went up against actors who stood in for his opponents.

“Gay and lesbian couples already receive benefits in Maryland, like hospital visitation, state health benefits, and tax breaks,” Baltimore Ravens center Matt Birk is seen saying in a video opposing Maryland's gay marriage law. “We don't need to redefine marriage.”

Kluwe responded that marriage has previously been redefined to accommodate society.

Societies “redefine it according to what the social mores are at the time,” he said. “We're not redefining marriage to take away someone's rights. We're redefining marriage to give someone rights. It's about freedom.”

An actor read a statement attributed to Minnesota Rep. Michele Bachmann, a strong opponent of gay marriage, saying that legal marriage for gay couples would result in “all schools teaching homosexuality” to children.

“I would say that that is a flat out falsehood,” Kluwe responded. “What we'll be teaching our children is tolerance. We'll be teaching our children that it is okay to be who you are.”

Kluwe debated the statements of opponents for about 90 minutes.
