This is a wonderful video, just under 7.5 minutes long, by Raymond Braun who travelled to Ireland for the vote. He travelled around and talked to people, both straight and gay, about what it meant to them. It was pretty awesome seeing the up-welling of support for marriage equality, enough so that there was an entire store in a mall selling just pro-equality items.
This is the first time a country has adopted marriage equality through a popular vote. Props to Ireland. I hope it spreads.
