Thats up to them. IN this country everyone, both gay and straight, have the right to marry whomever they wish as long as that person is not of the same gender, is not a minor, and is not being forced into the marriage.
I know what your point is but people are talking about a right being denied to only a certain demographic. The fact is no one has the right to marry a person of the same gender. We are all denied that right.
