I should really offer my opinion here rather than keep joking around.
I've grown up in a country where guns are very uncommon, those who have them can't get hold of them easily and have to go through a complicated process to even apply for a license. The only other way is converting a imitation gun into a real one (obviously illegal). Since gun culture doesn't really exist beyond illegal guns, I personally can't understand why anyone would want to buy an assault rifle.
That said, who am I to say the Second Amendment doesn't have any meaning today?
