From MATTHEW ROZSA’s article:
The researchers discovered that individuals who identified as “highly straight” but had latent impulses for sex with other men were far more likely to favor anti-gay policies. In addition, those men were also more likely to call for stricter punishments against gay people who commit petty crimes. “Not all those who campaign against gay men and lesbians secretly feel same-sex attractions,” explained Dr. Richard M. Ryan to The New York Times. “But at least some who oppose homosexuality are likely to be individuals struggling against parts of themselves, having themselves been victims of oppression and lack of acceptance.”
The explanation is pretty similar when talking about heterosexual sex scandals, such as the one involving Duggar. One study found that residents of highly religious and politically conservative states spent more money on Internet pornography than their less religious and conservative counterparts. And the states which banned gay marriage had 11 percent more porn subscribers. There is a solidly-established statistical correlation between social conservatism and higher rates of abortion, teen pregnancy, and sexually transmitted diseases — and nations that have more liberal views on sexuality generally have fewer sex-related health problems than countries that are more repressive.
All of this is because, as Dr. Christopher Ryan explained at Psychology Today:
If expression of sexuality is thwarted, the human psyche tends to grow twisted into grotesque, enraged perversions of desire. Unfortunately, the distorted rage resulting from sexual repression rarely takes the form of rebellion against the people and institutions behind the repression… Instead, the rage is generally directed at helpless victims who are sacrificed to the sick gods of guilt, shame, and ignorant pride.
