In the 1950s Evelyn Hooker realized that all extant studies of homosexuals were conducted on homosexuals who had been imprisoned for sex crimes, in therapy or committed to mental institutions, and so they were concluding homosexuals were sick because they only studied sick homosexuals. Her 1957 study, The Adjustment of the Male Overt Homosexual was the first to systematically examine homosexual men who weren’t in prisons or mental institutions or undergoing therapy and, surprise, surprise, discovered that if you study gay men the same way you study straight men they look pretty much alike.

In 2012 Mark Regnerus studied broken families with gay people in them, compared them to intact families headed by heterosexuals, and concluded that gay people make lousy parents, thereby proving that the religious right wants social science and the view of gay people to stay back in the early 1950s.
