> traditional concept of marriage

While it is correct that marriage has traditionally been a union of people of two different sexes, I think the root of the issue is that is not how many people perceive the tradition in reality. I, along with many people, view marriage as a union between _two people_ - regardless of gender. The fact that marriage has mostly always been across sexes is a side effect of centuries of homophobia/heteronormativity.

So saying that marriage is meant for a man and a woman does not compute for me. Trying to enforce that is _taking away_ from my concept of marriage.
