Well, for starters, we’re currently living in some pretty politically charged times. People are going to react, and over react, to calls for a revolution far more quickly than they might have 10 years ago.
I’m fairly well educated. I’ve read the Declaration of Independence. I love American History, even as a math teacher. As a kid, I avidly watched every and anything to do with Watergate, and spent the summer of Iran-Contra on the beach with a radio, listening to the hearings.
But I’m not sure I would recognize too many lines from the Declaration of Independence, once you get beyond the opening and the closing. I just googled it-- I’m not sure I could have correctly identified the source of a line like this one: “He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.” If it showed up on Jeopardy, the odds are probably 50/50 that I would get it right.
I think it has become a common game in our country, and perhaps elsewhere, to deride others for not knowing exactly what we know. We push ourselves up by putting others down. And of course, making fun of the generations to follow our own, to think of them as somehow less worthy, less intelligent, less giving-- it’s all great sport for some.
My guess is that the people in the OP know THEIR stuff-- what they need to know in order to make their lives work. And that they would have recognized the opening lines of the Declaration of Independence, the Preamble to the Constitution, the opening to the Gettysburg Address, and a good part of MLK’s “I Have a Dream” speech. But if they missed the opening tweets, the ones that readily identified the source of the rest of the quotes, they were reacting to a call for revolution.
But after a while most of us forget things we haven’t used in a while. So, while the Cosine of 45 degrees is a no-brainer for me, I would struggle-- a lot!!-- with the chemical symbol for Manganese.
NPR got lots of mileage-- first, they were Good Americans for posting the Declaration of Independence. Then, they got to make fun of all the others who didn’t have an intern handy to go find them all the actual words.
