This seems pretty remarkable to me, since it's rare to hear public apologies that aren't required by law or necessary to win votes. It would have been much more likely for this organization to simply dwindle away until they ran out of business and the last guy closed the doors and slinked away, never mentioning his former "career" to any of his new coworkers at whatever more normal job he ended up at. Not that an apology makes up for the incalculable amount of absurd pain the organization caused, but it's still a nice gesture.
This announcement of course dovetails nicely with the Supreme Court’s historic decisions. The Court is in step with public opinion, which has been changing fast, perhaps faster than for any other marginalized group in history. Here are some charts from the New York Times’ Nate Silver:
The first chart focuses on the U.S., and the second on the world. It's interesting that both articles focus on same-sex marriage, and in recent years it's intrigued me that this is the locus of our debate about gay rights. It's not that marriage isn't an important issue, but it's worth remembering that in previous civil rights movements in earlier decades and centuries, groups were fighting for equal representation in voting, in hiring and pay, and in ending violent acts (lynching, burning, you name it.) It's a sign of progress that those issues thankfully don't need to be the primary concern of this particular fight for equal rights today.
