And yes, the guy was an ex-Bircher. He said they kicked him out because he was TOO RADICAL!!! for them.
Carto wasn't the only Jew-hater to come out the Birch Society. Many people who later led Nazi or Klan groups did the same. One of the eleven men who with Robert Welch founded the Society was a rabidly racialist anti-Semite who also later left. Even the explicitly anti-chrstian atheist Ben Klaassen (founder of the "religion" now known as "creativity") started out in the Birchers.
Here's the point I'm trying to make. Unfortunately, despite what most FReepers think, many conservatives were at one time anti-Semitic and many anti-Semites were conservatives. The notion that "conservatism" means simply a minarchist philosophy of government and individualism is an extreme simplification of the way things really are.
Many avowedly Nazi organizations share some moral beliefs with decent mainstream conservatives. And they consider themselves on the "right;" not on the "left," as the Birch spectrum would have you believe.
But these groups' support of traditional morality has nothing to do with G-d. It's all because these are the "traditional values" of their ethnic group(s).
Even here at FR there are people who make a "western" ethnic identity more important than religion and G-d's commandments. It is unfortunately a fact of life that conservatives too often tend to do this.
