Section 1 of the 14th Amendment to the Constitution of the United States of America states:
"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."
Laws preventing marriage between two men or two women are unconstitutional. Homosexual American citizens are denied life and liberty by not having equal marriage rights. In these United States, all of its citizens deserve equality.
