A very succinct and fairly encompassing review of the relevant history. Well done.
However, it is not quite as resolved as your piece implies and I think this quote is fairly optimistic:
“In the end, the nine justices in black robes agreed that denying gay couples the right to marry was indeed a violation of their constitutional rights and dealt a fatal blow to those opposing same-sex marriage.”
The US Supreme Court is many things, but it is the most politicized court in a generation and I hope for a 5-4 decision in affirmation of the 9th's ruling. At worst, Scalia and his cohorts will find some excuse to send the decision back to the 9th for "further review" if they can muster the votes without resolving anything.
