On Wednesday, February 12, 2014, Comedy Central's program "The Daily Show" aired a segment about Russian crackdowns on gay rights activists before and during the Winter Olympics in Sochi. Daily Show correspondent Jason Jones interviewed one of the few gay rights activists he could find in Sochi and asked her, "are you hopeful that Russia can change?" Her response was: "I have to hope, because otherwise it's too depressive....I really do it just to not be ashamed of me, of my way of living. I want to look at the eyes of my children and my grandchildren, and say, I did all I could. As a quote from your--from an American TV show--it's called 'Angel'--there is a wonderful phrase there: 'If nothing we do matters all that matters is what we do.'" This line comes from the episode "Epiphany," during the scene when Angel is telling Kate about his recent realizations about how to help ease suffering in the world.
