How else could the accurately, clearly written Constitution end up so bastardized in spite of its accurate, concise language?
Coming from someone whose entire life and income is centered around the "accurate" use of language, would you like the language that applies to this very thorny truth that accuracy in language is illusion, and you must somehow deal with it ALWAYS?
One word: PRIORITIES.
The misuse of the word "machine gun" is of low priority here.
TOP priority is the misuse of language in the MSM, where "gangs" and "clubs" are used interchangeably, where "experts" are demonstrably so inept that either they have zero clue of who they are arresting OR they are dismal failures at catching violent criminals even when they're proudly wearing signs on their back identifying them as such (fewer than one in three of these so-called criminals had ever been arrested before).
Get your priorities straight and stop playing fetch the stick every time somebody throws an errant word at you.
