Any one have the actual study, esp how the questions are phrased and data on which students responded? Or what other questions did not have an exciting answer and so not reported on? "Most students who responded to a survey about free speech" suggests there may be a biased sample. "UW-Stout's Menard Center for Public Policy and Service ... The Menard family, a major Republican donor that founded the Menards home improvement store chain, donated $2.6 million to the center in 2019" maybe suggests there might be bias to the intent of the research too.
