I read a very interesting commentary from a anitgun guy (can't remember his name) that said if we still had the militia system in place we had in 1789 (which we don't) then neither anti nor pro gun folk would not like it.
The antis would be upset because ordinary folk would privately own FA and other military type weapons.
The pro-gunners would not like it because of the controls and inconveniences placed on them for mandatory (with penalities imposed for non-compliance) training and upkeep of the weapons.
Indeed, it was those very "inconveniences" that killed the militia system. Military life has really never been popular in the US unlike, say Germany, and our folk don't like that type of discipline which IMO is why we have an AV military.
