I don't consider 27 years old "a kid", and I don't agree with you that people should not open carry where it is legal. I admire those who open carry, because it helps everyone get used to it. But it takes courage, and willingness to be hassled at best, and maybe even stopped for hours by police and have your firearm confiscated.
Well, I'm 75, and I consider a 27-year-old a "kid" if he is going around making a big issue of open carrying, and legitimately inviting questions as to his common sense, when a small fee for a PA license, if he is a person not prohibited, will admit one without question to any place where legally allowed open or concealed.
Remember, a CCDW licensee can carry open any place he wishes. But some places are just not practical, convenient, wise, or popularly accepted. Being an agitator on principle may not be helpful to the cause at all.
But "kids" often don't understand that. That's what makes them kids. I respect a person who shows good judgment as not being a kid, whether 16 or 60.
Sometimes I exhibit poor judgment in answering comments on FR just to make a point. Maybe this is one case. But open carry campaigns in this atmosphere, especially at this movie, does not seem to be a wise thing. Flatulence in church, when it slips out inadvertently, is to be forgiven; but when deliberate, in-your-face, and flaunted, is wholly inexcusable.
With respect to those of a different opinion on this -- but I have mine.
