As the headline says, idiots.
There are more “idiots” than you think. I would guess that >50% of the people where I live think that Sikhs are Moslems. What the HELL do they teach in schools these days? Where is the money and the TIME going? The school year is much longer, the amount of money spent on education is probably 4x in real terms, and the access to educational resources VASTLY greater than it was when I was in grade school. I can comfortably state that most of my MIDDLE SCHOOL CLASS would know the difference.
