It is indeed a real problem. Everyone feels like they are entitled to be not only safe, but also "comfortable" at all time. No matter what. Nobody should judge you, nobody should disagree with you, nobody should make you feel bad about anything. This is a recipe to create highly dysfunctional adults.
Accepting conflicting opinions, facing rejection, standing for yourself without calling a twitter mob to the rescue, not seeking constant validation is part of being a functioning human being.
I'm wondering what is the agenda behind this trend. The author seems to think that it is to make sure students remain babies and stay in college as long as possible to avoid facing the real world. Could it really be something that petty? I started thinking that it could be encouraged by politicians to create a generation of babies that would feel better about dealing with a nanny-state.
