For about 2 and a half hours a large number of half-truths and bizarre claims of impending doom and conspiracy were expressed by average folks - claims about secret CIA projects using laser mind control devices to create deranged killers who are used to promote gun restrictions was one such theory, and more were also offered.
Not all claims were so bizarre but often the comments were based on errors and emotions rather than reality.
A Tennessee man who claimed to be a "tactical security expert" got his gun permits revoked after posting a video online warning he'll kill folks who might seek ownership restrictions. Oh, his "training" isn't actually certified by anyone. Just another maniacal mythmaker.
Gun myths are common though the anger aimed at any who might challenge the myths uncommonly powerful.
Southern Beale points out a few of them, including the nature of some "training" classes:
"The classes I took taught me almost nothing about how to defend myself with a gun. One, taught by a man who said he refuses to get a carry permit because “I don’t think I have to get the government’s permission to exercise my right to bear arms,” packed about twenty minutes of useful instruction into four long evenings of platitudes, Obama jokes, and belligerent posturing. “The way crime is simply out of control, you can’t afford not to wear a gun all the time,” he told us on several occasions."
More mythical history pointed out here.
It will be ridiculously tough to enact common sense gun laws since it appears there is a stunning lack of reality among all the myths.
