Among my fondest possessions is a personally autographed copy of the good Col. Cooper's classic book "To Ride, Shoot Straight, And Speak The Truth." While his occasionally-imperious style may chafe the urban-insecure/delicate-academic types, his strong opinions are heavily grounded in practical experience and common sense.
In addition to his invaluable "Principles Of Personal Defense," ANYTHING he's ever written makes a marvelous litmus test of latent liberal-pacifist Sheeple-think... simply because Jeff Cooper's intrinsic mindset drives 'em nuts.
If you doubt this, just give copies of his P.O.P.D. booklet to your, umm, "progressive" (*cough*) friends for Christmas. Then, stand-by for their indignant howls of outrage, snide comments... and sneaky little games/tricks to marginalize you, discriminate against you, and undermine your professional standing.
In short, Jeff Cooper's accumulated Street Sense, Been-There Warrior Wisdom, and old-fashioned values are a threat to those who wish to replace individual responsibility with intrusive collectivist programs "For The Common Good," disarm us, and destroy the U.S. with politically correct multi-culturalism.
