I agree. What’s wrong with the John Birch Society?
I'm going to say this respectfully, but I bet you either weren't born before the '60s, or you weren't old enough to remember it. Here's a link to a WSJ editorial published on the day of William F Buckley's death. It was originally written for Commentary Magazine and was to run a few months later in Commentary. Buckley effectively articulates (per usual) the problems with the Birchers, and his (as well as some others) campaign to marginalize them.
