That's decent of you to post the *.pdf file. Thanks, Rich.
From Denny Hansen's Briefing Room
“… my niece produced the text used by her class, Magruder’s American Government by William A. McClenaghan, (1985, Allyn and Bacon). As plain as day, right there on page 136 were the words, "The Amendment has no real significance today—except for its propaganda weight in arguments over gun control."
Holy Smoke! It's gonna take time to overcome this kind of propaganda.
