In this case I figure the label of “gun-owner” is considerably less specific to the crowd than that of “at a political rally, ranting about government conspiracies and The Evil Libruls”, and so I draw my conclusions about their stability from the latter label, only afterwards assessing and factoring in how much more or less reliable a person with a gun is than a person without a gun.
So, the logic is, “Wow, those guys seem unstable! And they have guns - yipes! Having a gun (open-carry) doesn’t make you more stable than average - but it does make you more dangerous. Ergo: flee!”
Heck, the crowd was small enough to be composed entirely of outliers anyway - and as I think the ‘armed mob’ thing is an obviously bad idea, that leads me to suspect that most of the sensible, responsible types elected not to attend, leaving this particular crowd of gun owners as likely to be composed of the most foolish, angry, and unstable gun-owners the area had to offer, as a matter of self-selection. Making assessments based on the activities of gun-owners-on-average almost completely useless.
I mean, Oakminster, you sound rational enough at the moment - would *you *strap on extra guns and go chant at such a rally?
