Kelly, Walt - Pogo Dailies Published in "The Jack Acid Society Black Book"

In the early 1960s, Walt Kelly took on the ultra-conservative John Birch Society with a series of strips dedicated to Mole and Deacon's efforts to weed out Anti-Americanism (as they saw it) in the swamp, which led them to form "The Jack Acid Society." The reference is to John Birch, who was killed 13 years before the creation (in 1958) of the organization that bears his name. The Jack Acids (the name is an obvious pun on "jackasses") modeled themselves on the only "real" Americans: Indians. Everyone the Jack Acids suspected of not being a true American was put on their blacklist, until eventually everyone but Mole himself was blacklisted.
