In today’s Wall Street Journal, we find an excellent op-ed by the unexpected duo of Michael Bloomberg and Charles Koch. Their subject is the erosion of free speech and tolerance on our college campuses. The foolish mania about “safe spaces” will only create graduates who are unwilling to listen to or even tolerate differing opinions, they argue.

As Paul Gottfried pointed out in this Pope Center article, leftist professors used to relish arguments. Now, unfortunately, most of them would rather just make personal attacks or silence those who disagree with them. Those bad habits have rubbed off on students.

Bravo to Bloomberg and Koch for addressing this key issue.
