I’ve heard some strange arguments against marriage equality, but the latest from Iowa Family Policy Center President Chuck Hurley is a doozy. Reacting to a new report on HIV and syphilis rates among gay and bisexual men, Hurley asserted,

“The Iowa Legislature outlawed smoking [in some public places] in an effort to improve health and reduce the medical costs that are often passed on to the state,” Hurley said. “The secondhand impacts of certain homosexual acts are arguably more destructive, and potentially more costly to society than smoking.” […]

“Iowa lawmakers need to pay attention to hard facts and not be persuaded by emotion laden half-truths,” he said. “Because of their unwillingness to correct the error of last April’s Iowa Supreme Court opinion, the Iowa Legislature is responsible for sanctioning activities that will lead to dramatically higher rates of HIV and syphilis in Iowa.”

Where to begin? Smoking increases the risk of heart disease, cancer, stroke, and various respiratory ailments, causing an estimated 438,000 preventable deaths every year nationwide. In Iowa, smoking directly causes an estimated 4,400 deaths each year, and secondhand smoke claims another 440 lives. Smoking causes about $1 billion in health care costs every year in Iowa, of which about $301 million is covered by Medicaid.

AIDS is a serious health threat in the U.S., but not on the same scale as smoking. AIDS has caused fewer than 20,000 deaths nationwide per year in the past decade. The total number of AIDS deaths in this country since the epidemic began is estimated at just under 600,000. I was unable to find statistics showing how many Iowans have died of AIDS, but according to this report for the Iowa Department of Public Health, 114 Iowans were diagnosed with HIV in 2005, and 79 Iowans were diagnosed with AIDS the same year. The numbers may have increased somewhat since then, but AIDS is nowhere near as “destructive” and “costly” to Iowans as smoking. Iowa’s syphilis rate is far below the national average, and none of the states with the highest syphilis rates permit same-sex marriages. If Iowa legislators want to influence the syphilis rate, they should focus on providing adequate funding levels for STD testing and ensuring that young people have access to medically accurate sex education.

Hurley’s argument is not only fact-free, but also illogical on several levels. He seems to think that allowing same-gender couples to get married is going to encourage many more Iowans to experiment with gay sex. Do you know anyone who decided to become gay because they knew they’d be able to get married? Has homosexual activity diminished in New York and New Jersey since those states’ legislatures declined to legalize same-sex marriage? Did California’s Proposition 8 reduce the number of gays and lesbians having sex there?

If Hurley is worried about promiscuity and sexually-transmitted diseases, he should be happy to see gay couples settle down and get married.

Contrary to the strange fantasies of the Iowa Family Policy Center crowd, the Iowa Supreme Court didn’t make the sky fall last April. Fortunately, most Iowans understand that our state legislators have more important things to do than overturn same-sex marriage rights. They also sense that giving legal recognition to the relationships of committed same-sex couples does no harm to other people. More than 90 percent of respondents in a statewide poll conducted last September said gay marriage had caused “no real change” in their lives.

Hurley’s position on gay marriage is more coherent than, say, Terry Branstad’s, but it’s also more detached from reality. Maybe his latest comments aren’t the worst argument ever against gay marriage, but they are certainly a contender.
