By Steve Sanders The year 2000 has emerged as the most critical period in the history of the gay rights movement. Over the next eight months, state legislators, the Supreme Court and the voters will determine in important ways how gay and lesbian relationships are recognized, how effectively civil rights laws can be used to promote homosexual equality and which side is ascendant in the culture war over America's most controversial minority. This Tuesday, California voters will decide a bitterly contested ballot initiative on whether that state should recognize something so cutting-edge it's not yet legal: marriage between members of the same sex. Meanwhile, legislators in Vermont are struggling with an order from that state's high court to grant gay couples the same rights as married heterosexuals. On April 29-30, tens of thousands of gays, family members and allies will descend on the nation's capital for the "Millennium March on Washington," a weekend of speeches, spectacles, performances and prayers for gay and lesbian equality. Later this summer the U.S. Supreme Court is expected to rule on only the third major gay-related case in its history, deciding whether state civil rights laws trump the Boy Scouts' policy against homosexual members and leaders. Finally, come November, voters' decisions on who controls the White House and Congress may decide the fate of a proposed national non-discrimination law, the future of the military's "don't ask, don't tell" policy and the tone on gay debates set by the nation's elected leaders. These battles loom as gays are enjoying steady gains in public acceptance and political clout. A new review of public opinion by political scientists Kenneth Sherrill and Alan Yang, titled "From Outlaws to In-Laws: Anti-Gay Attitudes Thaw," shows that while 56 percent of Americans still believe homosexual behavior is "morally wrong," larger majorities support equal job opportunities and laws against hate crimes. Opposition to gay equality in areas like housing, insurance and inheritance rights, and adoption has eroded significantly over the past two decades. And at a time when gays are coming out as never before -- in private, in public and on television -- polls show support for equality increases dramatically when people say they have at least one gay friend, family member or co-worker. But deep divisions over homosexuality remain, and no where more starkly than in California, where voters in the nation's largest state will decide this week whether to approve a law saying "only a marriage between a man and a woman shall be valid or recognized." The issue is moot right now: no state gives marriage licenses to same-sex couples. But the multi-million dollar media war over the so-called "Knight initiative" (named for its sponsor, Republican state Sen. William "Pete" Knight) has come to symbolize emotional political and religious differences over how society should treat its gay citizens. As if to underscore the issue's ability to polarize, Knight's son David revealed last fall that he is gay and estranged from his father. While gay marriage remains theoretical, the Vermont Supreme Court ruled last December that limiting the benefits of marriage to opposite-sex couples violated the "common benefits clause" of that state's constitution -- an unprecedented victory in the quixotic campaign to legally recognize gay relationships. Declaring gay couples' quest for protection and security nothing less than "a recognition of our common humanity," the court tossed a political hot potato to the state legislature, which must decide this spring whether to simply grant marriage licenses to gay couples, or erect an elaborate system of "domestic partnership." Domestic partnership would provide gay couples the same state-conferred privileges -- such as the ability to make medical decisions for partner, or inherit property in the absence of a will -- that married people get, while withholding the "m" word and the social recognition it implies. Legislative leaders have signaled they intend to focus for now on domestic partnership rather than expanding marriage. Unlike marriage, however, domestic partnership would not be recognized across state lines. Gays say it may represent a return to the "separate but equal" status the nation's legal system long ago rejected for blacks and other minorities. While Vermont deliberates, the U.S. Supreme Court will hear arguments on another flash-point issue: whether a New Jersey civil rights law can be used to prohibit Boy Scout groups from enforcing policies that exclude gays. The Scouts expelled James Dale as an assistant scoutmaster after learning he was involved with a gay student group at Rutgers University. Last August, New Jersey's highest court ruled the Boy Scouts were covered by a state law prohibiting discrimination on the basis of sexual orientation. The Scouts have argued they have a special right to discriminate because they are a private membership organization. Currently, only 11 states have laws that protect gays from various forms of discrimination. That could change come November. Democratic leaders have pledged to pass a federal law barring anti-gay employment discrimination if they regain control of Congress. The Democratic party has stepped up overt appeals to gays and lesbians, who make up an estimated five percent of the electorate -- as much as nine percent in large cities. In the presidential primaries, Democrats Al Gore and Bill Bradley have vied for invitations to gay community centers, fund-raisers, even on-line chats, and have denounced the military's policy on homosexuals. The Republican race between George Bush and John McCain, by contrast, seems like a contest to demonstrate who would take a harder line on issues like "don't ask, don't tell," marriage and adoption. Bush has waffled on whether he would appoint open gays to his administration and criticized the New Jersey Boy Scouts decision. Although McCain has had a cordial meeting with a gay Republican group and denounced figures like televangelist Pat Robertson as being outside the mainstream, he has endorsed California's Knight initiative and said of homosexuality, "It's a lifestyle I don't approve of."
