Openly gay Minnesota State Senator Scott Dibble has called on the Minnesota Vikings to throughly investigate former punter Chris Kluwe's claims that his gay marriage advocacy ended his NFL career.

“As the most popular sports league in America, the NFL has a huge influence on the attitudes of our society, especially young people,” Dibble wrote in a letter addressed to owner Zygi Wilf. “A failure to condemn discriminatory values by employees or remaining silent to claims of intolerance sends a signal not only to your own players and employees, but to all Americans, that such behavior is acceptable or condoned.”

In a scathing op-ed published last week, Kluwe said that he was fired by special-teams coordinator Mike Priefer, whom he called a “bigot,” and two “cowards”: then-head coach Leslie Frazier and general manager Rick Spielman.

Kluwe alleged that Priefer made several anti-gay comments in the course of objecting to his advocacy on the issue of marriage equality and quotes Priefer as saying during a team meeting, “We should round up all the gays, send them to an island, and then nuke it until it glows.”

Priefer immediately and “vehemently” denied the charges. The Vikings responded by hiring outside counsel to investigate the claims.

“It is important for you to know how much Chris Kluwe was appreciated for his candor, his humor and his courage in stepping up during an important moment in our state's and country's history,” added Dibble, a prominent figure in Minnesota's marriage equality debate. “If his perception of events are upheld, it would be a shame to fail to rectify what would amount to a grave injustice. Again, a negative message would be sent about what it means to stand up and speak out.”
