For reasons I don't fully understand, you seem to equate whether or not Zero carries NH to some fabricated (in your mind) erosion of gun rights in NH. Maybe you missed the overwhelming sweep of the House and Senate by NH Republicans in the last election cycle. Maybe you missed the pro-gun legislation passed in the last two legislative sessions. We didn't get all we hoped for, but the last time I looked, legislators were arguing over which Constitutional Carry bill they should pass. Perhaps you could point to similar legislative battles in MA in the last 60 years (your chosen timetable.)
I feel bad you are taking this so personally, but if you step back and evaluate it objectively, it does look like sour grapes. There have been three-quarters of a shitload of P&R Licenses issues in NH, and we can point to maybe five times they have been held-up/denied in some egregious fashion. That stretches the concept of a "trend of eroding rights," and it's what makes the sour grapes argument more compelling.
