Isn't that response a little over the top? Some Guy was merely saying that life's experiences are essential in a good voter.
I set the limit at 30, myself. At 18, I had a highschool diploma and stock-boy's job in a grocery store. At 30, I had an honorable discharge from the Navy, practical experience running a nuclear reactor, suvived a submarine collision at sea, had a hell of a lot of fun in the Philipines, collected an ex-wife and some ex-girl friends, an paid my own way though college for an engineering degree, some wonderful hangovers, stuck a knife in one guy in self-defense and practically strangled another for his assault on my girl friend, wrecked a few cars, and moved to a completely different state.
Life's experiences count tremendously. And voting is a responsibility too dangerous to give to just anyone.
