Wow, do Leftists still think they can fool anyone w/ this fallacy of origins argument? It's almost like the 2nd Amendment says "Right to bear *arms*", not "right to bear muskets" & many of the Founding Fathers were themselves inventors & had the foresight to know that technology would change, but axiomatic principles would not.
For the record, in that time-period, people had *repeating rifles w/ 20/21 round vertical hoppers* ( https://en.wikipedia.org/wiki/Girandoni_air_rifle ) & yes, privately-owned *warships armed w/ cannons*.
But sure, if we're going w/ your "if it wasn't *exactly* as the conditions of early America were at the time of the signing of the Constitution, it doesn't apply", I guess all the southern blacks can get back in the cotton fields, & gay marriage is off the books.
