How?

It is three and a half years since I was slammed by the sledge hammer which is "Brokeback Mountain" I thought I had shed all the tears possible until today I saw this video.
I can never listen to "I dreamed a dream" without tearing up so combining the two sent me over the edge. How can people say gay love is a lifestyle choice? How can they vote to deny same sex marriage? How can they deny the reality of our love? How can they deny that same-sex love is also a gift of God?
