Ed Brayton and Jim Burroway cover the story well, so check it out. I'll give you Ed's link here, which in turn links to Jim's analysis.
And as Ed so eloquently states, this is why it matters.
...that is important because we need to recognize that we are not fighting for gay rights only, we are fighting for liberty, full stop. The freedom from arbitrary governmental intrusions into the lives of gay people secures liberty not just for gays, but for all of us. This is not their fight; it's our fight, for all of us who love liberty and are willing to fight for it.
