Concealed carry ‘enabled’ by legislation (regardless of the process or requirements) is but another restriction on the Second Amendment.
One of the most uncomfortable elements of the Second Amendment, for left leaning quasi-conservatives, is the logical extension of its fundamental tenet that precludes even their ‘common sense’ restrictions.
To apply registration requirements of any sort simply does not pass logical muster, given the language of the Amendment. Likewise, the notion of limiting ‘types’ of firearms is on the same logical quicksand.
Firearms are a current technique. Used to be swords, knives, chained dogs, cobras on the grounds, trebochet, mangle, ...... a large wall (and so many people think those 12 to 16 ft chain link fences are unsightly and should be banned from residential areas yet they are your first line of defense against armed briggands).
This "right" is not just about firearms.
