Are there any political issues or civil liberties you actively promote or defend (through volunteer/grassroots efforts)? What are they? Do most of your friends feel similarly?
Marriage rights for all is an important non-issue. I say that because it shouldn't be an issue, and those who speak out against it, have no real justifiable reason to say such rights to certain populations will bring down the world. It hasn't yet, since these very people live together anyway. Once this right has been extended to all, it will be shown to have been an unnecessary civil dispute all along.
