When referencing basic human rights such as the freedom of speech and association, liberty, and equal protection for all citizens in court, the term civil rights is used. Civil rights are the rights belonging to an individual by virtue of citizenship. By nature, these rights include the fundamental freedoms and privileges guaranteed by the 13th and 14th Amendments to the U.S. Constitution and by subsequent acts of Congress including civil liberties, due process, equal protection of the laws, and freedom from discrimination. Despite the fact that the existence of homosexuality has been traced back to the first signs of human documented history, the framers of the American constitution made note that the civil rights listed in the drafted Constitution were not to be denied on the basis of sex, race, or religious belief, but failed to include a provision stating the unconstitutionality of discrimination against citizens on the basis of sexual preference. All in all, nothing in the U.S. Constitution grants homosexuals the right to marry, nor should it be interpreted as such.
