The lower courts however turned out these decisions in record time, which was very appreciated.
		
		
	 
Yes, the lower courts have given us gay marriage.
The Supreme Court has waited. And waited and waited and waited. When it was given an opportunity to decide, it found a way not to decide. When it was given multiple opportunities to correct this mistake, it chose to ignore them.
I do believe, of course, that SCOTUS will eventually sanction what the lower courts and the nation in general have already decided. And, when that happens, SCOTUS will be lauded as having caused a great improvement in the quality of life in America. 
But SCOTUS never really made that decision. It just waited until no other decision would make much sense. That is better, of course, than deciding 
against gay marriage. And a lot of people will insist that the wait was necessary; that the nation needed  time to prepare itself for the shock of acknowledging that certain people have rights. Bullcrap.
SCOTUS would have been more effective in its public role as a mediator of justice by supporting gay marriage early and enthusiastically. As it is, the support is late and subdued - almost an afterthought. You really do get the impression that the court did not want to support this example of social justice, but simply could not find a way around it. 
Our public institutions serve us well when they help guide us to ultimately historical understandings of justice. They are terrible when they attempt to guide us to ultimately historical understandings of injustice. The present example of gay marriage is not (yet, at least!) a case of SCOTUS guiding us toward injustice. But it is an example of the court attempting to delay the arrival of obvious justice, and I see that as problematic. This court not only has done a bit to delay the arrival of gay marriage in America, it cannot even bring itself to announce its (presumably positive) decision in a supportive fashion.
I will be overjoyed by a finding in our favor. But I am underwhelmed by the insight and leadership of this court.
