Uh, how about the right to get married to the person you love?

Somewhere there is a list of about 1000 federal benefits that married people get, most of them financial.

How about the right to keep your house and belongings when your partner dies?

How about the right to be at the bedside and make medical decisions for your sick partner?

If you are stuck on Constitutionally guaranteed rights, how about the right to equal treatment under the law, which would cover everything above?

How about the right to privacy? GfS, since you think it's all right to discuss other peoples' sex lives on an internet forum, perhaps you'd like to share the details of your sex life with us? Or are you unwilling to swallow the medicine you're handing out?
