Growing acceptance of homosexuality means a decline in social stigma associated with same-sex relationships, and a consequent shift in the politics of coming out. The more people come out, the more accepting people are around them, and the more accepting the public becomes, the more people come out.
There is, he says, a vocal, virulent -- and sometimes violent -- anti-gay movement, but it doesn't negate decades of opinion surveys that show a marked increase in tolerance in most Americans' attitudes toward gays and lesbians. In 1998, for example, a Gallup poll found that only 33% of Americans thought that homosexual relations between consenting adults should be legal. By 2007, that figure had risen to 59%.
"Society is beginning to say that being gay is not such a big deal," Gates says.
As more gays come out in more places, the diversity of homosexual politics and lifestyles will come out with them, and the tolerant will multiply.
