Some of you might not like this post but I find this a troubling trend:

A dozen people carrying guns, including at least two with assault rifles, have been spotted mingling among protesters outside a convention center in Arizona where President Barack Obama was speaking.

Phoenix police said the men carrying guns at Monday’s event did not need permits, as the state of Arizona has an “open carry” law. No crimes were committed, and no one was arrested.

One of the men carrying a rifle declined to be identified but told The Arizona Republic that he was carrying the assault weapon because he could. “In Arizona, I still have some freedoms,” he said.

Yes, you can and yes, you do.

Frankly, though, it is one thing to exercise a right and another to attempt to intimidate those you disagree with. I firmly believe in the right to conceal-carry for self-preservation. I have to waver, though, on slinging on a rifle as you protest an event — regardless of who the speaker is — because it naturally coarsens the conversation and serves no justifiable purpose other than to attempt, by visual means, to silence the other side by an implied threat that you will use whatever means possible to achieve your side’s goal.

More than that, it provides ammunition to liberals who — rightly or wrongly — claim that “the Right” is preparing to use violence against them and the President.

Sometimes, discretion is the better part of valor.

I’m guessing that some of you will respectfully disagree.
