LISTEN: Texas Pol Claims Same-Sex Couples Won't Survive on a Desert Island

Far-right Republican congressman Louie Gohmert of Texas is still making a case against marriage equality, continuing to use the argument that same-sex couples can't reproduce without assistance.

Gohmert repeated this argument last weekend to journalist Michelangelo Signorile, saying that if same-sex couples were put on a desert island, they would not survive, Signorile reported in The Huffington Post.

Signorile approached Gohmert at the Conservative Political Action Conference, where the congressman laid out his case:

"If you want a long-term study on what's the best building block for the family, you can take couples, man and wife couples, put them on an island where they have everything they need to sustain a society. Take all male couples, put them on an island, everything they need to survive. Take all women couples, put them on an island, and all they need to survive. Come back in 100 years and see which building block has been most effective in perpetuating their society and I think it'll tell you all you need to know."

Gohmert made similar comments last year. "We could take four heterosexual couples, married, and put them on an island where they have everything they need to sustain life," he told a youth group then, reported Right Wing Watch.

"Then, take four all-male couples and put them on an island with all they need to sustain life, take four couples of women, married, and put them on an island, and let's come back in 100 to 200 years and see which one nature says is the preferred marriage," he concluded, essentially arguing that the ability to procreate should be a deciding factor in whether a union is legal.

Gohmert, a frequent honoree in The Advocate's Phobie Awards, has a history of over-the-top antigay statements. In the House of Representatives in 2009, he said LGBT-inclusive federal hate-crimes law would offer protections to people who are "oriented toward animals" or "toward corpses, toward children."

Back in 2010, Gohmert testified against the repeal of the military's "don't ask, don't tell," policy, since he believed gay soldiers would be unable to control their "overt feelings of homosexuality" and end up assaulting fellow soldiers. Gohmert equated marriage equality with bestiality during a right-wing conference call in 2013. In 2014, he claimed that LGBT advocates are like Adolf Hitler's Third Reich, bent on silencing those who disagree with them.
