A recent survey of 2,000 Americans by Cato Institute/YouGov found that 62% of Americans say “the political climate these days prevents them from saying things they believe because others might find them offensive”.
This is up from 2017, when 58% agreed with this statement.
People who defined themselves as staunch liberals self-censored considerably less:
“Strong liberals stand out, however, as the only political group who feel they can express themselves. Nearly 6 in 10 (58%) of staunch liberals feel they can say what they believe”.
