Texas Rep. Louie Gohmert, a Republican, explained last week that gays can't have “what nature says is the preferred marriage,” because if placed on an island they would die out.

Gohmert made the statement while speaking at the Washington, D.C. conference of the college chapter of Phyllis Schlafly's Eagle Forum.

“We could take four heterosexual couples, married, and put them on an island where they have everything they need to sustain life,” Gohmert said. “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.”

Gohmert also said that Supreme Court Justices Elena Kagan and Ruth Bader Ginsburg “ought to be impeached” for not recusing themselves from the case that struck down gay marriage bans in all 50 states after officiating the legal weddings of gay couples.

"I think they ought to be impeached. I think they ought to be removed. And until Congress shows that we do have some say in the Constitution over the courts, the abuses are just going to get worse,” he said.
