Arkansas State Sen. Jim Holt (R-Springdale) likes to demagogue. In 2005, Holt targeted undocumented immigrants, partnering with a man with anti-Semitic views and ties to white supremacist organizations in an effort to pass hard-line anti-immigrant legislation. (Holt later distanced himself from Joe McCutchen of Protect Arkansas Now.) Now, Holt's target is gay people. Holt told National Public Radio in August that there "are thousands of studies, actually I've got over 10,000" of them that show "the homosexual family or the environment is problematic for the child."
As pointed out by Media Matters for America, a reputable watchdog website, the 10,000 figure would only be possible if a such a study had been released every day for the past 27 years.
Holt was reacting angrily to the July decision by the Arkansas Supreme Court that overturned that state's ban on gay foster parents. The court ruled that the ban was based on a particular morality rather than science, and that no research on sexual orientation had found a negative effect on foster children's welfare. Scientific studies from the American Academy of Pediatrics and the American Psychological Association support the ruling.
Holt said he picked up the 10,000 number from another anti-gay demagogue, Focus on the Family founder James Dobson. Dobson made that remarkable claim in his 2004 book, Marriage Under Fire: Why We Must Win This Battle. According to Media Matters, Dobson provides no source whatsoever.
