I think there is a (thankfully) very small segment of the gun community that has decided to take their stance on the offensive and to do so with absolutely no regard for how others feel. I'm talking about the groups of people who open carry AR-15s or whatever in Target or Walmart or whatnot.
Let's face it -- even though you have a legal right to do so you have just about zero actual reason to do so other than to intimidate and basically be an adult bully.
I'm not a fan of this behavior, especially as it ratchets up tensions and just makes it that much more likely an incident will occur.
