A friend of mine is an atmospheric science professor who publishes research on climate change modeling. His work is descriptive. He regularly gets hate mail from conservatives. Another friend of mine is a medieval history professor. When they teach intro courses they discuss more than just european perspectives on medieval history. They regularly get students complaining that their essays on why the crusaders should have killed every single muslim person get bad grades. Being descriptive is nowhere near sufficient to keep conservatives from screaming at professors.
