re: This is a very potent argument against the "2nd amendment means militia" talking point

This will definitely be lost, but how does the DC vs Heller (using as precedent) affect the govt from taxing people for gun ownership? If the second amendment states that a well regulated militia is to be, but new (or old) taxes prohibit citizens from owning guns, but adding in the 14th amendment guaranteeing equal protection, how can gun taxes be legal.

Yep, not even attempting to do a deep read here.
