When I was in grad school, I was pretty centrist: more liberal than most of the students from BYU (where I’d just finished my bachelor’s) but more conservative than most of the students at MSU. I had an odd experience one day when a fellow student far, FAR to the left from where I was teasingly chided me for a Facebook post I’d made defending Common Core from one of my BYU friends who was convinced it was a communist plot.
