A few months ago I participated in a rally in support of traditional marriage. The rally was sponsored by the Chinese Churches of San Francisco. My guess is that a few thousand people lined the streets. The participants were mostly Asian with a smattering of other races represented. I joined in with a few of my Korean friends who were also participating in the rally. Most people were wearing red t-shirts with the words "Marriage = 1 man & 1 woman". On the back side of the shirt was the same thought expressed in Chinese characters. Many traditional-marriage supporters were also waving signs with the same message. The organizers discouraged participants from making home-made signs in order to set a positive tone for this event. We were encouraging passing cars to honk if they supported our cause. There were many honking cars and I believe we gained the attention of city officials.

Of course it is hard to be "for" something without inferring what it is you are "against". Obviously what we were rallying against was the practice of granting marriage licenses to homosexual couples in San Francisco. It is a difficult thing to demonstrate opposition to a "sin" yet express love to a "sinner". Perhaps this is what keeps many good people away: a fear of being perceived as a hater of people. And yet, I believe that these few thousand people accomplished their aim with grace. The only hateful words that I personally overheard were spoken by counter-demonstrators against supporters of traditional marriage.
As I read opinion in the newspaper about "same-sex marriage", one comment that upsets me most goes like this: "Same-sex marriage is a civil rights issue. Our homosexual unions are no different than marriages between a man and woman of different races. Just as mixed-race marriages are now accepted by society, so will same-sex marriages be accepted one day". Well, I am one part of a mixed-race marriage and my marriage is not at all like a same-sex marriage. As any sociologist will tell you, racial categories are a human invention. At the biological level racial differences are superficial. Gender differences are deep and biological in nature. They are written into the DNA of each human cell.
I know that at one time, my marriage to an Asian woman would not be accepted by society. Societies throughout history have set rules about how close a marriage partner may be (second cousin / in-law) and about how distant a marriage partner may be (different tribe or race). However, these rules are man-made and change from time to time and from place to place. Marriage has always been understood as an institution between an man and a woman. I believe that the creator of humans made them male and female from the beginning. To redefine "marriage" to include same-sex couples would be like redefining "north" to include "south". Marriage is a yin and a yang. It cannot be a yin and a yin.
