I chose the year 2015 as a high-water mark of sorts, as it was the same year the landmark Obergefell SCOTUS decision came out - a moment that American history will likely record as the moment that SCOTUS's decades-long arc of expanding civil rights and liberties for average Americans stalled out.
That said: The Vice-President who authored this moving tribute to the Obergefell decision?
Hey! He's the President now!
Maybe there's still hope!
