"You are graduating at a time when there is a full-fledged assault on truth and reason. Just log on to social media for 10 seconds. It will hit you right in the face. People denying science, concocting elaborate, hurtful conspiracies theories about child abuse rings operating out of pizza parlors. Drumming up rampant fear about undocumented immigrants, Muslims, minorities, the poor. Turning neighbor against neighbor and sowing division at a time when we desperately need unity. Some are even denying things we see with our own eyes. Like the size of crowds. And then defending themselves by talking about “alternative facts.”"
