From my understanding, 'marriage' is a religious thing. But, why can't we change that and make it about, 2 people who want to bind and celebrate their love and life together?

We live in 2011, regardless of religion or whatever, times have changed, people have evolved, so I think it's times for the attitude against same sex marriage, to change. Gay people are here to stay, and they should have the right to marry their loved one, as much as anyone else!
