If a single poor desicion from less than 20% of the US population makes the entire US population of 300,000,000 total idiots, then I suppose you're right, KappaWing.
I personally am sick of being called stupid because of the election of a president when I was too young to vote.
Well it was the percentage who bothered to go out and vote and represent themselves. Someone who was able to vote but did not has no right to complain when other countries assess the median citizen of his.
Of course, we are special circumstances as we are too young to vote, but an arbitrary limit on age has to be set somewhere. Granted, I think 18 is too high. I think it should be 16, the same age you can drive, drop out of school, join the military, etc.
I think other countries realize that we are not a nation of brainwashed idiots united behind our leader(s), we have a two party system with one party only inching above the other, although the way they can throw their weight around without due restraint doesen't give an impression of moderation.
As of this election, the median voting American.... is not an idiot.
