It's a "divide and conquer" issue.
Just as people in the past believed it was "wrong" and "immoral" to allow a black person to marry a white person---there are people in the present who believe it is "wrong" and "immoral" to allow a gay person to marry a person of the same sex.
These people are close-minded bigots who allow their prejudices to prevail over common sense. Of course, they deny that they are bigoted or prejudiced. They claim that they have "valid arguments" for opposing gay marriage. "I'm not against gays, but ______."
These people are incapable of understanding the wrongfulness of imposing their beliefs on others when doing so deprives others of equal rights under the law and relegates others to the status of second-class citizens. They cannot be persuaded that there is no legitimate state purpose in denying homosexuals the right to marry the person of their choice (a person of the same sex) when the state grants heterosexuals the right to marry the person of their choice (a person of the opposite sex).
These people are incapable of understanding 1) that their beliefs are the product of bigotry and prejudice; and 2) that imposing their beliefs on others through the operation of laws is both wrong and unconstitutional. Accordingly, the issue of gay marriage is a divisive issue. It is also a distracting issue.
Here's a satire of how the neo-conservative politicians use divisive, distracting issues to win votes:

Tales of Horror from Dr. Distracto
JB
Dr. Distracto: All right, children, it's 6/6/06, the day of the Beast, so gather round, while I regale you with tales of horror that are sure to curdle your blood!
Children: Yippie! Tell us the one about the big flood that destroyed New Orleans! Tell us the one about the deficit that ate the economy! Tell us the one about the war in Iraq!
Dr. Distracto: No, children, I don't want to talk about those things right now. I have something *much* scarier.
Children: Hurray!
Dr. Distracto: If you don't vote Republican in the next election, gay couples will burn American flags at their weddings!
Children: Noooooo!
Dr. Distracto: Then they will drive Mexican nationals across the border in hybrid cars!
Children: Noooooo!
Dr. Distracto: And then they will take all the Mexicans to abortion clinics, and force them to watch Al Gore's documentary on global warming!
Children: Oooooh, that's so scary, Dr. Distracto. I'm so frightened I can't think about anything else!
Dr. Distracto: Mission Accomplished.
Children: Oh no, not those words! Now you're scaring me again!

Fortunately for America, the persons who are bigoted and prejudiced against gay persons are a dying breed. As time passes, political attacks upon gays will be less and less effective. Today, it would be political suicide for a candidate to run for office on a platform that includes banning interracial marriages. The same will hold true for present-day and future politicians who run for office on a platform that includes banning gay marriages. The political tide is turning against those who still hold those bigoted and prejudiced viewpoints against gays.
Future politicians will be forced to identify and pursue other divisive and distracting issues.
