Well, gays can get married in all 50 states and all 50 states must recognize those marriages. Cheif Justice Robert's in his disenting opinion wrote, that the decision had nothing to do with the constitution. Justice Alito wrote against the fact that a small majority of justices can invent new rights and impose them on the rest of the country. These two dissenting opinions are among the best in my opinion. I also think these opinions have merrit.
