Another part of the problem is the obsession with social media, and the "never forgets" nature of the internet. A half-ish century ago, on most campuses, your political/religious/philosophical beliefs could wander all over while you were at college, and it didn't much matter. Vs. now? My sense is that the kids all know a 24/7 lynch mob is waiting if they ever deviate from canon. And that studying the current canon, and stage-managing their professed views as that keeps changing, are their most critical tasks.
