Can you ban a marriage that never existed?

This post was in response to an article titled "California Upholds Gay Marriage Ban." My posting was promptly removed. Here it is:

I find the bias in these kinds of news articles interesting. Why is it that when people try to preserve the integrity of traditional moral family values that they are "banning" something that was never legal? I think you'd be hard-pressed to find any kind of long-established legal precedent for homosexual marriage. Marriage is, by definition, between a man and a woman. Look it up in any dictionary that was written before the powers that be decided to practice political correctness. Marriage is a binding and holy covenant made between a man and a woman. We should remain true to our Constitution, which was written that we might obey God rather than man. Not only is it proper to follow the moral integrity of years past, but it is needful to preserve it for posterity. Children are entitled to have clarity on these issues. They need the freedom to choose to abide by God's laws.
