Donald Trump is scheduled to speak this week at the Values Voter Summit, the annual confab hosted by the Religious Right powerhouse the Family Research Council. While Trump has claimed that he will be a better “friend of LGBT Americans” than Hillary Clinton (just “ask the gays”), his appearance at VVS shows the extent to which he has cozied up with some of the country’s fiercest opponents of LGBT equality, going so far as to offer them their pick of Supreme Court justices.

Many of the summit’s organizers and speakers have a long history of anti-LGBT rhetoric and promoting anti-LGBT policies, from denigrating gay and lesbian armed service members to falsely linking homosexuality with pedophilia. In fact, a glaring number of VVS participants have defended laws criminalizing homosexuality in the U.S. and around the globe.

While the Religious Right has changed its messaging in recent years to claim that conservative Christians in the U.S. are facing persecution from LGBT rights activists, it was not long ago that many of the same groups were fighting to preserve laws that made gay people criminals—and some still support enacting these policies at home and abroad.

The Family Research Council, which is the chief organizer of the conference, is a case in point. In 2003, when the Supreme Court was considering the constitutionality of Texas’ ban on “sodomy” in the landmark Lawrence v. Texas case, the FRC filed an amicus brief on behalf of the state. When the court ruled against Texas in the case, the FRC called it “a direct attack on the sanctity of marriage” and the group’s president, Tony Perkins, declared, “What’s at stake here is the very foundation of our society, not only of America but all Western civilization.”

Not only has Perkins defended state laws criminalizing same-sex relations, he once defended a notorious anti-gay bill in Uganda that at the time he discussed it proposed life in prison or even the death penalty for people who have sex with someone of the same sex. Perkins lauded this bill as an effort to “uphold moral conduct that protects others and in particular the most vulnerable,” criticizing President Obama for opposing it. The FRC even spent $25,000 to lobby Congress about a resolution denouncing the Ugandan bill—the group later claimed that it didn’t oppose the resolution, it just wanted to make its language less friendly to gay rights. In 2011, FRC asked its members to pray to give Malawi the “courage to withstand U.S. coercion” and maintain its ban on homosexuality.

Peter Sprigg, a senior fellow at the FRC who will have a speaking slot at this weekend’s summit, has perhaps been the most clear about the organization’s views on the subject. Asked by MSNBC’s Chris Matthews in 2010 if he thinks “we should outlaw gay behavior,” Sprigg replied, “Yes.” In a 2008 television interview, Sprigg mused, “I would much prefer to export homosexuals from the United States than to import them into the United States because we believe homosexuality is destructive to society.”

The American Family Association, another sponsor of the Values Voter Summit, likewise backed Texas in the Lawrence case, writing in the amicus brief that a law like Texas’ could prevent the “injury caused to the public by same-sex sodomy” and would even protect the gay people it targeted by sparing them “illness, disease and death resulting from [their] conduct.” That same year, the AFA published an essay lamenting that the disappearance of sodomy laws showed that “Judeo-Christian views” were being abandoned in favor of “moral relativism.” In 2011, then-AFA spokesman Bryan Fischer said that homosexuality should be a “criminal offense.”

First Liberty, another sponsor of the event, likewise backed Texas in the Lawrence case (under its previous incarnation as the Liberty Legal Institute), with the group’s leader Kelly Shackelford—also a speaker at this year’s VVS—declaring that there is “no constitutional right to engage in homosexual sodomy.”

Other figures at the Values Voter Summit have also supported criminal bans on homosexuality.

Rick Santorum, who will have a speaking slot, has boasted of his opposition to the Supreme Court’s Lawrence decision. Family Watch International, which is sponsoring a booth at the event, frequently works with some of the world’s most repressive governments to keep LGBT-friendly language out of UN documents and has supported harsh anti-gay legislation in Nigeria. Liberty Counsel, which will also be sponsoring a booth in the summit’s exhibit hall, backed Texas in the Lawrence case and defended a homosexuality ban in Malawi. Radical anti-LGBT activist Matt Barber said on a Liberty Counsel radio program he co-hosts that the U.S. should adopt a ban on “homosexual activist propaganda” similar to Russia’s. Fischer, the former AFA spokesman, also advocated enacting a similar law in the U.S.

Many Religious Right leaders have rallied behind Trump because he has promised to give them their ideal Supreme Court justices and lower court judges. Very recent history shows that these groups aren’t just interested in using the courts to reverse marriage equality—which would be harmful enough on its own—but also to severely roll back years of hard-won legal protections for LGBT people. Trump says that he’d be better for the LGBT community than Hillary Clinton—but we doubt that he’ll bring that message to the Values Voter Summit.
