Yes...as well as two men or two women...in more states than it is reserved for only men and women.
Not legally, according to Baker 1971 as reaffirmed by Judge Sutton this month. Lower federal courts do not enjoy the luxury of overturning judgments at the SCOTUS level. The law defaults to the the last judgment on the matter. Both Baker, 1971 and Windsor 2013 affirm state's choice in approving or disapproving gay marriage. No state told by a lower federal circuit judge that it must honor gay marriages against its electorate's Will has legal gay marriage. And they never have. Not in 1971. Not in 2013.. Not now, until SCOTUS revisits its judgments in Baker and Windsor and overturns itself.
MIght want to do some research on the SCOTUS. There are two ways that a SCOTUS precedent becomes inactive. One the SCOTUS directly setting aside a prior judge. The second is doctrinal changes that render a prior ruling inapplicable anymore. As noted in the Circuit Court rulings by the 10th, 9th, 7th, and 4th Circuit Courts - that while the SCOTUS has not directly set aside Baker (from 1971) there have been a number of doctrinal changes that have occured which have changed the legal landscape.
Baker was a one-line dismissal of an appeal for want of a "Federal question" at the time. There were no states that recognized SSCM and there was no Federal law on the issue. That has changed:
1. Congress passed DOMA in 1996 which inserted the Fedreal government into the equation, in other words it created a Federal issue.
2. State began recognizing SSCM in 2004 when Massachusetts became the first state to establish Marriage Equality. Since then a number of states have passed SSCM through action so the legislatures and at the ballot box - in addition to those where SSCM exists because bans on SSCM were found unconstitutional.
3. The SCOTUS recognized in Romer v. Evans and Lawrence v. Texas that States targeting homosexual for discriminatory treatment was unconstitutional.
4. Finally in United States v. Windsor the SCOTUS ruled discrimination by the Federal government against homosexuals for not recognizing legally valid Civil Marriages amongst same-sex couples as unconstitutional and eviscerated the logic that was presented to justify such discrimination. The SCOTUS noted in Windsor that while States had great latitude in family law, that such laws must still recognize Constitutional guarantees of equal protection under the law.
Very telling was you insistance just a few months ago that the cases on appeal to the SCOTUS would be a slam dunk, that the SCOTUS would accept the case and slap down the Circuit Courts. In fact you were wrong. They did no such thing. As a matter of fact they let each of the 4 Circuit Court rulings stand and each one (IIRC) addressed the Baker question. If it was as you said, all the court need to do was accept the case, reiterate the Baker position - and this would be all done with.
But they didn't, they let the Circuit Court ruling stand.
