It seems that a recent survey shows that 23% of young Americans think that the Holocaust is a myth and 10% believe that Jews were responsible for it. I bet if they repeat this survey in 3 or 4 years they will find that a high percentage will say the Holocaust was the brand name of a beer that German soldiers use to drink back in the 30s!
No wonder then that an American Professor at Notre Dame University has written:
"My students are know-nothings...their brains are largely empty, devoid of any substantial knowledge that might be the fruits of an education"
