“Cancel culture is a very grave threat to American freedom,” White House aide Stephen Miller told the Larry O’Connor radio show shortly after a Cato Institute survey showed that most Americans are silencing themselves amid online hostility. “The share of moderates who self‐​censor increased 7 points from 57% to 64%, and the share of conservatives rose 70% to 77%, also a 7‐​point increase,” according to Cato’s July survey. “Strong conservatives are the only group with little change. They are about as likely now (77%) to say they hold back their views as in 2017 (76%).”
