Gay/Lesbian bars fail for the same reason "straight" bars do: Not enough paying people to keep the lights on. It's not a conspiracy or some new form of oppression that Lesbian bars across the country are failing. In fact, the bars closing are an indication that gay acceptance/awareness has been succeeding to such a degree that gay people don't have to go to "themed" bars just to feel accepted/safe anymore. They can go anywhere they want, which was the goal from the get-go of the gay rights movement. People, especially gay people, should be seeing this trend as society moving forward and an overall win.
