Trifling stuff. If you want to find real ignorance come to Tokyo. I asked a couple of 2nd year high school students to find The Philippines and Indonesia on a map and they had no idea. They also didn't know that Brazil was in south america, and naturally had never heard of Lenin, Marx, Roosevelt, Mao, Apollo moon landings or Einstein. God only knows what they are taught at ' school'.
I wish I were joking but I'm not. I'm 59.
