Activists in the gay rights movement have often been accused of trying to ride the tail of the black civil rights movement. There is no doubt that there are some similarities and crossovers. Both attempt to right injustices and advance equality.

But there are also distinct differences, and in some instances, issues pertaining to discrimination based on race clash with those based on sexual orientation and gender identity.

Californians are about to test this fragile relationship.

Last May, a California state court recognized that same-sex couples have the same constitutional right as those of opposite sex to choose life partners and marry. It was an important and courageous decision on the part of the courts, and an encouraging sign for same-sex marriage advocates across the country.

California being, well, California often leads the nation in matters of social and cultural change.

But tomorrow, Californians will get a chance to decide for themselves on whether or not they approve of same-sex marriages. Same-sex marriage advocates across the country will be watching this closely, including here in New York.

Proposition 8, if approved, will rewrite the California Constitution to define marriage as a legal union between one man and one woman.

The money that has poured into this debate on both sides is staggering - millions toward a fight that rivals important mayoral and senate races.

But the final decision may be in the hands of California's African-American voters.

If African-Americans head to the polls in the numbers expected, it could be bad news for same-sex marriage advocates.

Many African-Americans hold conservative views on sexual orientation. Some black religious and political leaders continue to refer to AIDS as a homosexual disease. Even on an international level, gay travelers are advised to be cautious when visiting Caribbean countries like Jamaica.

Senator Barack Obama has stated that he does not support Proposition 8. Senator John McCain says he does.

Tomorrow Californians will decide not only the definition of marriage, but the meaning of equality, too.

And it is incumbent on those who ask for understanding, to be ready to give it as well.
