"The moral of the recent melee at Middlebury College, where students shouted down and chased away a controversial social scientist, isn’t just about free speech, though that’s the rubric under which the ugly incident has been tucked. It’s about emotional coddling. It’s about intellectual impoverishment.
Somewhere along the way, those young men and women — our future leaders, perhaps — got the idea that they should be able to purge their world of perspectives offensive to them. They came to believe that it’s morally dignified and politically constructive to scream rather than to reason, to hurl slurs in place of arguments." …
Outside of college, people are sorting themselves into what are effectively political bubbles (both left and right leaning), so this may not be unique to some colleges.
It is only temporary. Once these kids leave college and get to the real world, then they well realize that there are people with different views from them, and they have to accept it.
