The right to pursue happiness, remember?
is described in the declaration of independence, which is not a government document. it is part of our national heritage, but it was not produced by the united states of america and has no binding power over american laws. sorry.
however. the fact that
Inheritance rights
Insurance
Taxes
Child custody
Child support
Alimony
Domestic violence
Adoption
Property inheritance
Family leave
Suing for wrongful death (and any other tort or law related to spousal relationships)
Hospital visitation
Health care decision-making
Durable power of attorney
these
protections of the law are available to some citizens in some relationships with consenting adults and not all citizens in all relationships with consenting adults is
sufficient to demand
equal protection under the law which
is a binding law of the united states of america.
Section 1. 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.
...(stuff about rebellions against the state and amending the 3/5ths rule omitted)
Section 5. The Congress shall have power to enforce, by appropriate legislation, the provisions of this article.
btw. due process of law refers to eminent domain and the confication of property or rights from those who have committed crimes. it does not mean 'except when you make laws restricting rights because of "tradition"'.
