Sometimes we gun owners are as bad as the gun banners when it comes to living in our own little dream world. Our dream world consists of RKBA and Right to Self-Defense and Heller ruling. Somehow all of that is supposed to be a magic elixor that shields us and our "rights" from public opinion.
Well, unfortunately the real world of our "rights" in our current political setup is made up of two universal truths:
1. What is constitutional or unconstitutional depends upon the decisions of the supreme court rulings. The individuals on that court are appointed by the political party in power at the time of an opening on that court.
2. The enforcement of laws that either regulate or protect our rights depends upon how vigorously the politcal party in power chooses to view the importance of a particular law. A law can be pushed far past it's original intent or it can be conveniently ignored or enforced in such a lax manner that it is in effect non-existent.
(I do recognize that our govermental system has checks and balances, but when any party has a huge majority for an extended period of time, those checks and balances are greatly weakened.)
Given the above and the fact that the political party in power depends upon public opinion, it behooves us to get our heads out of the clouds of "Our Rights" and recognize that "stupid is as stupid does".
I currently live in Tennessee and have watched the S - L - O - W progress of the state govermental process to allow handgun carry in general and, just lately, legal handgun carry in our state parks in Tennessee. We can argue forever about how this clown's actions were legal and his right to do so. The fact remains that it would take very little movement of the mainstream of Tennesse voters to put us right back to the days when state parks were off limits to handgun carry. The majority of Tennessee voters are neither pro-gun or anti-gun. They can be gently pushed in our direction with common sense arguments or abruptly pushed in the other direction by sensationalism by the news media.
IMHO (well, maybe not too humble

) we can choose to drink the kool-aid of our omnipotent "legal rights" or we can choose to step away from the actions of individuals such as this person. If we choose to defend his actions, we aid and abet the potential defeat of political candidates that are favorable to gun owners in general. If we step away, we will move him to the group of fringe elements that do not represent gun owners in general.
As one of my least favrorable radio personalities used to say, "That's my opinion, it ought to be yours!".
