Unaffectionate

I'm a girl whose sexual orientation leads her to other girls. I'd love to be able to marry someone, but...I won't be able to, because people have big "problems" with it. I was debating this in another forum, and not ONE person gave me a good reason why not to allow it - except for religion. State marriage...What about that? Religion should not interfere with loev and marriage; after all, not all gays are religious
