Human Rights Voting

I decided to post this alone for clarity:

English was a big class though, we learned our topics for a small three page research paper. To prep us for it, we were read what some of the human rights were. One of the rights is, as stated by the Universal Declaration of Human Rights:

Article 16

1. Men and women of full age, without any limitation due to race, nationality or religion, have the right to marry and to found a family. They are entitled to equal rights as to marriage, during marriage and at its dissolution.

Article 7

All are equal before the law and are entitled without any discrimination to equal protection of the law. All are entitled to equal protection against any discrimination in violation of this Declaration and against any incitement to such discrimination.

My question is: Why doesn't this apply to homosexuals? Keep in mind, I do not believe that gay marriage is biblically correct, but legally it should be. It bugs me that America is revoking the rights of gays just because of their sexual preference. To answer this question, there will be a poll in the side, to discuss, please comment and tell me what you think.
