I am not saying the laws don't need to change. I think they do. But they need to change for all of us.
Let me put it a different way. In the eyes of the law, marriage is a union between two people who wish to share legal rights. For example, if I die, that person has rights to my property. If I am in the hospital and am incapacitated that person has the right to make choices for me. There are some tax breaks because we share the same home, and thus get a break for cost of living.
These are the legal rights gay people want. What I am saying, is government never asks if I am fucking the person I have these rights with.
Tradition dictates that the person you CHOSE to be your life partner happens to be the person you form a romantic bond with, but nothing says it has to be. The right I stated above I could want to give to my father, if I chose to never be romantically involved with anyone again, and chose to spend the rest of my life (or his) living with him.
I should have the right to pick a man, just like I have the right to pick a woman, to share those rights with.
Another example, would be if I chose to marry a 70 year of woman who happens to be a lesbian, and we never see each other in person. legally I could do that, so it's obviously not based on some form of love, and just legal.
Make that legal thing allowed between two men. Not just for you, but for everyone.
We both don't have that right. Makes it pretty damn equal to me.
