The right wing fringe has been around a long time. The references in the songs may be dated but lyrics are still fun. Back then the John Birch Society was the primary hard right fringe group.
You cannot trust your neighbor or even next of kin
If mommie is a commie then you gotta turn her in
Oh, we’re the John Birch Society, the John Birch Society
Fighting for the right to fight the right fight for the Right
