I guess. The better question might be why it's getting indulged on campus. An extension of the trend towards gutlessly pandering to students, or do a faculty really agree with this stuff? It's hard to believe that there could really be widespread agreement with shielding students from any and all negative emotions, but maybe I don't understand the modern college faculty outside of STEM.
Most (though not all) are coming from small liberal arts schools. Perhaps those schools are going with "all publicity is good publicity."
