Did the Founding Fathers envision the Bushmaster? Almost...

18. That's a frankly absurd assertion

the first of these may have been manufactured in 1779 but they were in limited production in Europe and not common; the "right to bear arms" as envisioned in the Second Amendment would have been limited to such weapons as were used by the militia (smoothbore muskets and Kentucky rifles). And in any case it matters not one whit what the mythical and apparently godlike "founding fathers" may or may not have approved of, because the America of the late 18th century was a significantly different country, socially and otherwise; the entire US population was 3 million, frontier settlements were under real threat of attack from hostile natives, and there was no standing army or national guard (hence the "citizen militia", which also included regular drills and training).

The Founding Fathers also approved of slavery, denying suffrage to women, denying citizenship to Native Americans, and denying democratic representation to the majority of Americans. So what they approved of or not isn't really a very good argument and hasn't got a lot of relevance to modern society, more than two centuries later, which has evolved in many ways then unimaginable.
