There are plenty of wider discussions to be had about this whole thing. Ensuring that faculty are good teachers, which includes the empathy to broach difficult subjects with sensitivity and moderate debate. The provision of welfare services to students to assist them to make the most of their studies.

Listening to a minority whose refusal to engage and demand that others cave in to their views harms society - and in many instances harms the very people making the demands. Victims of sexual assaults need a justice system that is better at understanding issues of consent, victim blaming and the harm victim may be put through by a trial - and how to weigh that up against the right to confront your accuser. Ethnic minorities need a society better educated in history, understanding of cultural differences and similarities who continue to be more progressive and accepting than previous generations.

Perfect example! Law is one career where you can learn everything you need to know by reading books (ok, maybe all of them are that way..). Yet legislators (many lawyers themselves) in several states have introduced new laws to limit licensure only to those who have degrees. This would've excluded notables like Lincoln, Jefferson, Darrow, Marshall.

"I see on your C.V. you've written 'The United States Declaration of Independence' -- nice job! Oh but no JD? Tsk. Next!"

EDIT: though he was awarded 'honorary' degrees from several institutions. Would those pass muster these days? ;)

Avoiding exposure to ideas that challenge your own is not a good strategy for becoming an effective researcher.

This is rather disingenuous. According to an article in the NYT [1] she just had her job title changed in 2004, from 'Engineer' to 'Engineering Specialist.' Her salary and status did not change. See the excerpt below:

    Instead, Ms. Finley, who never finished her degree, fell
    into a newly created classification: engineering
    specialist, an hourly position.

    Her overall pay did not change, and she is now eligible
    for overtime.

> But the change still irks Ms. Finley; she must mark down her arrival each day, her half-hour of lunch and the time she leaves to go home.

> “It’s a demotion,” she said. “No one wants a demotion. We want to be treated like we deserve. But it’s true. I don’t have a degree.”

Nathalia Holt, a science writer who wrote a book about Finley and others, also considers it a demotion:

I'm not going to reject the ideal of college as a place to expand intellect because one common use is as a trade school.

You may say they have, by setting up trade schools, whatever they are. If the trade schools are not doing enough, that's the problem of the trade schools, rather than of the universities. If the trade schools can provide good enough education, employers will recognize credentials they provide. If employers don't recognize them, there must be something missing from their education. The piece missing may well be what universities want the students to learn: communication with those you don't like.
