OK, yes, I teach political science. And I accidentally wrote inches instead of feet. I think I was going to put the inches, which was not quite 2 feet, but rather 18-20 inches. And then I decided to round up. In my haste, I must've produced that type. Please oh please forgive this ignorant immigrant who grew up using the metric system instead.
I do admit that I'm ignorant about a great many things. And, yes, the US education system is pretty poor. I have to contend w/ students who can barely read or write and seem to have no motivation or appreciation for study. So I can empathize w/ your statement.
But people are also allowed to make mistakes, right? It snowed almost two feet in 24 hrs. Although I'm originally from a tropical country ... I still know that that is a lot of snow. The people on TV called it a blizzard. Does that count? ;-)
BTW, I have no hard (or hurt) feelings. ;-)
