I think it goes back to the gay-themed shows and shows with gay stars "Will & Grace" and Ellen Degeneres. After they became popular if you disagreed with them you were suddenly a bad person. But before that change in the popular culture the biggest change that led to all this was when the American Psychological Association took homosexuality out of their book of mental disorders. That was way back in 1973. From that point on it was no longer considered abnormal by the psychological community. The backstory on that goes back to the studies Alfred Kinsey did and were published in 1948 and 1951, but what they don't tell you is that he used pedophiles for his information, including prisoners and pedophiles on the street who were literally having sex with BABIES. A few years ago actor Liam Neeson tried to turn Kinsey into some sort of hero.
