First: Good article, good points, and I agree, "just because we CAN does not necessarily make it a good idea." Thanks to ZA for bringing this up.
Second: It is a consideration for all. Not every soccer mom will see things the same way the gun fraternity does. OPTICS is the current word in the political sphere, and the dude strolling among the customers at the farmer's market is not portraying the general Second Amendment true believer in a very good light. We are all "smeared" by association in the minds of those who may originally have been on the fence or even with us somewhat, but have somehow, been put off by the spectacle (spectre) of a man with a rifle which the media has been harping on . People in general, have been indoctrinated to become very nervous when a "civilian" is armed in public.
Third: I carry, but concealed. I see - for me, anyway - no advantage in displaying the fact that I am carrying. I also have the notion that it may be less to my favor to have the presence of that firearm on my person known and observed. "Nobody's business but my own".
If I have a political point to make I have done it by visiting my legislators in their offices, by writing letters, op-eds, and by appearing on live TV to express my views and to debate the laws.
