Back in August, I was enjoying happy hour at Merchant's in Pioneer Square after a busy work week, when a guy in a gorilla suit named "Chef Bigfoot" came in with a camera to interview the owner. Apparently, he releases videos of interviews with bar owners on youtube:

Specifically, when Roe was decided, it did not create an absolute right to abortion, but created a limited right to abortion (further limited in future cases) that ultimately allowed some states to enact abortion restrictions that have effectively eliminated abortion as an option for many women in the United States.
I just don't see how creating a fundamental right to marriage that encompasses lesbian and gay couples could allow states to enact similar laws that would limit access to marriage for gay and lesbian couples. In other words, the legal outcome of this case would limit the political process options available to marriage equality opponents in a way that Roe did not.
