BobS. has a review and critique type post up on the recent Starbucks response to Open Carry activism in their stores. He gives all sides a close look and asks useful questions. You should go read.
My response in his comments:
As we in the US continue our debates over the means and methods of enacting our rights, which often extend into disputes regarding the basic meaning of those rights themselves, we all ought to keep firmly in mind that we deliberately (if often seemingly unknowingly) do so in possibly the most public forum possible. This is a good thing in and of itself (as it reinforces the very concept of "rights") and also encourages the interest and attraction of those who don't experience the reality of our contentions in their daily lives. I will not argue for the idea that we should alter our arguments as a result, only that we should acknowledge the presence of the audience at our debates by presenting our points and contentions in as clear and open a fashion as we are each able.
And then go have fun shooting safely together after.
Update 1:12 PM, same day: this from No Lawyers - Only Guns And Money seems pertinent.
