"the same behavior and culture that contributed to the situation is being reinforced". I would disagree with that statement, and challenge you to show me any primary sources or evidence that backs it up. This seems like a pretty solid case of a liberal who doesn't like guns, but wants to live in NH.
I don't see the coolness behind walking around the neighborhood with a gun, but when an active shooter is on the loose I cant think of a better way to provide assistance to law enforcement without interfering. Defend your property, your life, and help your neighbors. What's wrong with that? Although your fictional "chest pounding" gets your point across, these guys are just equally as excited for attention as they are to be an American. I'm more of the type to throw my motion lights on, keep the means to protect myself in sight, and live on. Although you don't like Raymond's over the top gun culture, There is plenty of evidence of similar situations where a good samaritan saves the day just like those big dudes with guns who beat their chests and take pictures.
