In a speech to a group of young conservatives last week, Rep. Louie Gohmert, R-Texas, called for the impeachment of Supreme Court Justices Elena Kagan and Ruth Bader Ginsburg in retribution for their ruling in favor of marriage equality, and insisted that a study trapping gay couples on an island would prove that gays and lesbians can’t have “what nature says is the preferred marriage.”

Gohmert, speaking at the Washington, D.C., conference of the college chapter of Phyllis Schlafly’s Eagle Forum, said that Justices Ginsburg and Kagan “ought to be impeached” for participating in the marriage equality case after officiating the legal weddings of same-sex couples.

“I think they ought to be impeached, I think 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,” Gohmert lamented. He warned audience members that the Supreme Court wants you to “forget what Moses said God said, forget what Jesus said God said, we’re God and you go by what we say.”

He then suggested a study to prove that same-sex couples can’t have “the preferred marriage”:

We could take four heterosexual couples, married, and put them on an island where they have everything they need to sustain life. 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 told the audience that there’s “a case to be made” for impeaching President Obama, although he admitted he “hadn’t really thought about it” until reading a book by extreme conservative author Andrew McCarthy.
