The John Birch Society consistently said that the Soviet Union was evil incarnate.
And they were of course right.
Even a blind pig finds an acorn occasionally. The JBS was also famous for their belief in the Illuminati, controlling world history from the shadows, off-stage. Do you buy that too?
Unfortunately, the Birchers adopting a cause tended to undermine it. You couldn't call for the impeachment of Earl Warren (which was richly deserved) because the Birchers, vocal support for that had successfully "kookified" it. The same, unfortunately, with "Get the US out of the UN and the UN out of the US," a statement with which I wholeheartedly agree.
