Where you read "safety" in this article and other discussions of the issue, it's illuminating to substitute the words "regard as full human beings."
Contexts that don't regard certain classes of people - those with a history of this lack of regard - as full human beings are going to be considered obsolete by today's undergraduates. That's just a given. Repair these contexts and universities would see a lot of these problems go away.
There are, of course, contexts you can't repair - namely, works that have value but were made in, or contain, obsolete contexts. The recontextualization work here can be difficult, it's true, but universities and professors that don't do it are going to be hearing about it.
