re: #10 EPR-radar
It depends on the definitions being employed of “responsible gun owner” and “irresponsible gun owner”.
It is a tendentious (but defensible) move to silently use the NRA’s definitions of these terms. NRA ideology has all gun owners as by definition “responsible gun owners” unless/until they commit a gun-related crime. Thus the hooting and hollering described in the OP is necessarily from “responsible gun owners” (so defined), since there is no evidence that these people have committed gun-related crimes.
Ah, well I am not silently using the NRA definition. My use is more pragmatic than rhetorical. Safe & legal procurement, handling, use and storage.
