Argument: Many faith groups welcome gay marriage
Buddhism has many sects that celebrate gay relationships freely and encourage legal marriages.
At the 1996 Unitarian Universalist General Assembly, delegates voted overwhelmingly that because of "the inherent worth and dignity of every person", same-sex couples should have the same freedom to marry as other couples.
America's Reform Jewish rabbis gave their formal, theological blessing on same-sex marriage in 2000.
Jews in general Beliefnet.com - "As the most liberal group of whites in America, Jews already support laws protecting homosexuals from discrimination in housing, employment, and other aspects of public life."
Dutch clergy made a massive shift toward overwhelmingly favoring its national gay marriage laws: A survey conducted in 1989 when the Danish government legalized gay marriage revealed that 72% of Danish clergy were opposed to the law. A survey conducted in 1995 indicated that 89 percent of the Danish clergy now admit that the law is a good one and has had many beneficial effects.
Scott Bidstrup. "Gay Marriage: The Arguments and the Motives": "2. It offends everything religion stands for. Whose religion? Many mainstream Christian denominations, to be sure, and definitely most branches of Islam and Orthodox Judaism, but outside those, most religions are unopposed to gay marriage, and many actually favor it. When the Mormon church arrogantly claimed to represent all religions in the Baehr vs. Lewin trial in Hawaii, the principal Buddhist sect in that state made it very clear that the Mormon church didn't represent them, and made it very clear that they support the right of gay couples to marry. That particular Buddhist sect claims many more members in Hawaii than does the Mormon church. In a society that claims to offer religious freedom, the use of the power of the state to enforce private religious sensibilities is an affront to all who would claim the right to worship according to the dictates of their own conscience."
