I'm as anti-Birch as you can get, but that is simply untrue. The John Birch Society was and is a "palaeoconservative" organization. While they are libertarians on economic issues they are very socially and morally conservative. One of their ad hoc committees was the Movement to Restore Decency.
The Birch Society is primarily made up of three types of people: Rushdoonyian "reconstructionist" Protestants, sedevacantist Catholics, and Feeneyite Catholics. Despite the fact that their founder was an evolutionist Unitarian who rejected orthodox chrstianity (and despite their claimed neutrality in religious matters) they essentially push the aforementioned three religious philosophies as the answer to all the problems of the world.
I think it depends when and where you are talking about. You may well be right about the current situation. But the Birch Society was not pro-life, for instance, back in the early days.
