Michael Bloomberg's Commencement Speech has infuriated safe space needing leftists on college campuses.

The most useful knowledge that you leave here with today has nothing to do with your major. It’s about how to study, cooperate, listen carefully, think critically and resolve conflicts through reason. Those are the most important skills in the working world, and it’s why colleges have always exposed students to challenging and uncomfortable ideas.

The fact that some university boards and administrations now bow to pressure and shield students from these ideas through “safe spaces,” “code words” and “trigger warnings” is, in my view, a terrible mistake.

The whole purpose of college is to learn how to deal with difficult situations — not run away from them. A microaggression is exactly that: micro. And one of the most dangerous places on a college campus is a safe space, because it creates the false impression that we can insulate ourselves from those who hold different views.

Think about the global economy. For the first time in human history, the majority of people in the developed world are being asked to make a living with their minds, rather than their muscles. For 3,000 years, humankind had an economy based on farming: Till the soil, plant the seed, harvest the crop. It was hard to do, but fairly easy to learn. Then, for 300 years, we had an economy based on industry: Mold the parts, turn the crank, assemble the product. This was hard to do, but also fairly easy to learn.

Now, we have an economy based on information: Acquire the knowledge, apply the analytics and use your creativity. This is hard to do and hard to learn, and even once you’ve mastered it, you have to start learning all over again, pretty much every day.

Keeping an open mind to new ideas is essential to your professional success — just as it’s crucial to our collective future as a democratic society.

We are witnessing a disturbing change in the nature of American politics: a rise in extreme partisanship and intolerance for other views.
