I mean, I think that colleges are not responsible for the mental health of their students, at least to the degree it has been demanded the last few years - the whole 'safe space' concept has gotten out of control. The whole point of college is to learn and be exposed to new ideas, some of which will be uncomfortable and you're supposed to learn to deal with that. Colleges aren't completely indemnified from how students are exposed but the recent demands have been "don't expose me to things I'll disagree with".
