Ya know, just like everything else, everybody (even some pro-gun people), has an axe to grind. I have stated before that if things got bad enough for me to have to carry a long-gun over my shoulder, then nobody would give a crap because everything would be so bad, that just about anybody would be doing the same.
I don't like seeing this sort of thing because, to me (and I could very well be wrong), it shows a certain amount of mental instability to walk around with a long-gun strapped on, unless your hunting, or target shooting, or the "end of days" just happened. I'm a gun guy to the max, but if I would have been there, you can damn well bet that I would have been watching that dude close. Paint me stupid, but that's just me.
What ever happened to a society where people had some common decency and common sense. A long time ago, when even gun safety and shooting sports were a part of the school day (meaning most people were "gun friendly"), nobody did this sort of thing UNLESS, there was a real deal reason to do so. To me it's just "over the top", rebel without a cause sort of thing to do...just like ANTIFA, anti-gunners, or anybody else that is trying (in the wrong way), to draw attention to "their cause" and themselves by acting out.
I might get some heat for feeling this way, but I still believe that we still live in a somewhat civilized society, and even though us gun owners have a target painted on our backs by a lot of different sides, we still have a certain obligation to uphold to not be like the rest of the "rebels without a cause".
