I sense (from some other identical postings on the internet that the author has another specific open-carry axe to grind, in/pending litigation - but it happens too often that someone takes a position that "you damn CC people are screwing with my OC rights." I think you should do both but my opinion doesn't matter. Kommifornia is so f'd up that - as states used to fight for shall-issue permit laws - CA is like little county fiefdoms in a country all their own, fighting their county sheriffs.
Given the actual narrow scope (San Diego County) of the plaintiff's attempt to chip away at the commie glacier that is CA law I don't necessarily share the author's view that all those who filed amicus briefs on behalf of the plaintiffs are to blame. There are at least a couple of other more relevant core issues:
It's Kalifornia. (c'mon YGBSM)
It's the 9th Circuit. (same)
