What has changed since you were in college, is that everyone is much more hooked into a network, where every misguided thought or utterance is broadcast to everyone on the network, and immediately pseudo evaluated through likes/views/retweets/upvotes etc. That was never the case, when I went to college and said/thought/did misguided things all the time.

It's the wrong architecture to educate anyone. The only thing such environments, do is produce insecurity, defensiveness and rebellion on large scales. The reaction to which is "safe spaces, trigger warnings, and microaggressions". And then we get reactions to those reactions, rather than focusing on the underlying change in architecture that has happened.
