Minnesota Vikings punter Chris Kluwe has called the arguments of gay marriage foes invalid.

Kluwe is profiled in a cover story for Minneapolis-St. Paul alternative City Pages.

The 30-year-old 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.

While Kluwe's advocacy goes back a ways, it was the recent letter in response to a Maryland lawmaker in which he stated that allowing gay nuptials wouldn't turn him into a “lustful cock monster” that turned Kluwe into a marriage equality spokesperson.

Esera Tuaola, a former Vikings player who came out gay in 2002 after retiring, compared Kluwe to Martin Luther King.

“I teared up,” Tuaola said of Kluwe's letter. “For me, it was like Martin Luther King's I Have a Dream speech.”

Kluwe dismissed the arguments of opponents, calling them not logical.

“You see all these arguments against gay marriage, and they all kind of logically boil down to: 'It makes me feel icky,'” he told the paper. “That's not a valid logical argument! Like, tell me that gay people getting married is going to cause someone to steal your garage door opener, or it's going to cause your dog to poop in your front yard. I can argue against that!”
