I initially posted this diary as a comment in FogCityJohn's valuable diary on many of the legal issues arising with respect to the Log Cabin Republicans v. United States case, Judge Virginia Phillips's injunction against enforcing DADT, and the Ninth Circuit's motions panel's current consideration of the case. He said that he'd prefer that I take the discussion elsewhere, as he was interested in legal issues rather than political questions of motivation. So, I'm starting a separate diary.
It won't be clear what points I'm addressing from reading my comments in isolation. You should first read his "five myths"; you may want to open a second window. Out of respect for his preferences, though, please discuss my response here rather than there.
