"He who does not think himself worth saving from poverty and ignorance by his own efforts, will hardly be thought worth the efforts of anybody else." -- Frederick Douglass, Self-Made Men (1872)
To clarify, this isn't about whether or not marriage is a "right". It's about whether discriminating a marriage based on gender is unconstitutional, similar to how doing so based on race is unconstitutional thanks to Loving v. Virginia.
If States control the privilege of who can officially marry and receive benefits then the privilege should apply to all couples. I often hear people say that homosexuals have the right to marry someone of the opposite sex but that is irrelevant, as virtually all state constitutions make no mention of the gender of those to be married; in fact, most constitutions don't mention marriage at all. The exception to this, of course, are the recent amendments via state majority votes or legislative powers. Non-constitutional law is what regulates marriage so the states have the power to create the additional right for homosexuals.
Modern equal privilege is either applicable to all civil rights situations or it should be tossed out altogether. Marriage is about families and efforts to block legislation granting homosexual couples marriage rights is only in turn damaging their ability to manage their families and raise children in a stable environment.
Technically, marriage is not a Constitutional right.
Good reason to get government out.

Equal protection of the law is a constitutional right. Marriage is a form of protection the law offers, so it is constitutionally required that it be applied equally regardless of sexual orientation.
SOTUS took the time to look into *why* a racial requirement was instituted.
If the reason behind the racial requirement were valid, interracial marriage would not likely exist today.
Just because something discriminates against race/sex does not automatically mean it's wrong to do so.
