EXCLUSIVE — A new survey sponsored by Yale University’s Buckley Institute shows again that disturbing majorities of college students have no appreciation for liberty and, worse, that they can’t even think logically.

The national poll of collegians by McLaughlin and Associates, which will be released Tuesday, is reported exclusively here.

The results of last year’s Buckley Institute survey left me so “bile-filled” that I wrote that “today’s college students are proto-totalitarian ignoramuses” because 51% of the surveyed collegians would not necessarily look askance at “physical violence” being used to prevent the airing of views they find “hateful.” This year, that number is up to 53% (with a record 45% agreeing violence might be OK and another 8% unsure).

And this year, for the first time in the nine years of the survey, a plurality agrees it’s OK to shout down a speaker (with another 10% not willing to rule it out). For the first time ever, an outright majority, 51% to 38%, favors “speech codes” to regulate expression on campus. A plurality of students say they can’t even be close friends with someone affiliated with a different political party than themselves. For the first time ever, a plurality believes that political opinions from other students that they find “offensive” should be reported to school administrators, and a plurality thinks people making such remarks should be required to undergo “sensitivity training” or “re-education.” A full majority think there are certain topics that administrators should prohibit from being debated on campus.

Living down to the now-cliched but useful nickname of fragile snowflakes, students by an astonishing 65%-27% margin say professors should be required to provide “trigger warnings” for uncomfortable class discussions.

And that’s just on topics related to free speech and the unfettered exchange of ideas. The left-wing views on race, gender, economics (socialism over capitalism, 37%-31%), and leniency for shoplifters (which they see as a “victimless crime”) probably merit a whole separate column.

Yet apart from the views themselves, one mind-boggling aspect of the survey is the bizarre lack of anything approaching logical consistency in many students’ views. It’s as if they don’t even know what words mean, akin to calling raindrops “dry” or calling fire “cold” — or worse, if they know what “dry” and “cold” mean but don’t have the intellectual capacity to understand that those words contradict rain and fire.

Here’s why: At the exact same time the pluralities or majorities of students say they hold the attitudes mentioned above, every one of which is an abridgment of free speech and antithetical to the ideals of the First Amendment , even larger majorities claim to value free speech and the amendment that protects it. By a 78%-14% margin, students say the First Amendment should be followed and respected, and by a 69% to 26% margin, they say it is more important for a college to encourage free speech and intellectual diversity rather than preventing offensive dialogue. And an overwhelming 85% say that hearing opinions with which they disagree will prepare them to be better leaders.

Obviously, the numbers on those three questions sound encouraging. Yet when asked specifically, as noted above, significant percentages of students who say colleges should encourage free speech also, at the very same time, support speech codes, speech disruption, and even violence against unwanted speakers. How can a third of college students be so ignorant, or so unable to connect cause and effect, that they say they value free speech but then want it simultaneously banished?

What’s next — massive support for trials by jury at the same time they advocate summary executions without hearing evidence? Or maybe a commitment to democracy while supporting a dictator for life?

These kids are not all right. If this sort of disdain for basic free expression, especially when combined with such pathetic irrationality, is what the nation’s future holds, then the republic may be doomed to extinction.
