Great post! I am a more comfortable with concealed carry, but I live in a poor-to-middle class mostly black neighborhood which is strongly leftist. I suspect that if residents saw somebody with a gun around here they would automatically assume you were up to no good. Unfortunately, that would not be an altogether incorrect assumption based upon past experience in this area.
Nevertheless, I have nothing personally against open carry by citizens. I just think some folks would have a larger learning curve in getting used to it.
Now that you mention it, the few comments I do get are usually from blacks. Always positive though; typical question is what kind of license would they need to open carry? Here in VA the answer is they don’t need one at all.
