I agree with most of your posts and I think you're smart. However here I disagree. A US politician catching up with the population is definitely a big deal, as politicians are far from public opinion on most crucial issues. I don't have any respect for Obama, and I have no more now than before this announcement; but this is a monumental achievement of popular activism and of LGBT courage and commitment (not Obama's), and we should recognize that.
