Okay, this is one of those weird political battles where Libertarians are insulted on so many levels, we don't quite know where to start.
First of all, a Libertarian government wouldn't have such a thing as a Surgeon General to begin with. But if we're going to have such an office in the federal government, then we sure as heck shouldn't give that office to someone so blinded by dogma that he ignores all scientific and medical evidence proving that "reparative therapy" simply does not work.
You're an M.D., Dr. Holsinger. Act like it.
