It’s legal in Massachusetts and Connecticut. It will be legal in Iowa and Vermont by the end of 2009. It was legal for almost six months in California. Gay marriage — c’mon citizens of Michigan, all the cool states are doing it.

April has been a triumphant month for equality in marriage. Vermont’s legislature overrode a veto by Gov. Jim Douglas and voted to allow same-sex marriage. The vote came on the heels of a unanimous Iowa Supreme Court decision striking down a 10-year ban on same-sex marriage as unconstitutional.

The vote by the Vermont legislature diminishes one of the main arguments used by opponents of same-sex marriage, that rulings on marriage have been made by unelected court officials.

Justice Mark S. Cady writing for the seven-member Iowa court wrote, “We have a constitutional duty to ensure equal protection of the law.”

The American Civil Liberties Union said the Iowa Court decision is the third court case to treat governmental discrimination against gay people as a serious constitutional problem. The ACLU said in an April 10 newsletter that the main argument in opposition to gay marriage is for religious reasons, but pointed out that the Iowa court said that state government can have no religious views.

Remember that little thing called the separation of church and state? Religion should not justify a law excluding gays from marrying. The Iowa opinion should serve as an eye-opener for Michigan:

“The statute at issue in this case does not prescribe a definition of marriage for religious institutions. Instead, the statute declares, ‘Marriage is a civil contract’ and then regulates that civil contract …  Thus, in pursuing our task in this case, we proceed as civil judges, far removed from the theological debate of religious clerics, and focus only on the concept of civil marriage and the state licensing system that identifies a limited class of persons entitled to secular rights and benefits associated with marriage.”

In 2004, Michigan, along with 10 other states, passed a constitutional amendment to ban gay marriage. The proposal that passed 59 to 41 percent said that “the union of one man and one woman in marriage shall be the only agreement recognized as a marriage or similar union for any purpose.”

At least we can be proud of our state for finding a convenient loophole for equality. When we are that afraid to live and let live, let’s write it into the state’s constitution.

Historically, cultural norms evolve. At one time, issues like women’s rights or civil rights were hotly debated, but today, acceptance is commonplace. We are at a historical moment where once again we are debating an issue of discrimination, this time on gender.

In a posting on a legal blog, Andrew Koppelman, a law professor at Northwestern University, said that the same-sex marriage movement must now be acknowledged as “one of the most rapidly successful social movements in the history of the U.S., revolutionizing the law in an enormous part of the country in less than 10 years.”

Michigan’s 2004 amendment is a nasty stain on our reputation and credibility as a forward-thinking state. Five years ago most of us weren’t registered to vote. But we are now and it’s time for another vote. This time when we fill in that bubble we should consider the importance of equality and pursuit of happiness over our fears and prejudices.
