There's a related Atlantic article on victimhood culture that mentions a related point. College kids aren't the first group to do this, they're just the loudest and have taken it to the logical extreme. You see similar tones in the "War on Christmas" nonsense from certain Christian groups. How anyone can seriously be offended or worried for their culture by the design of Starbuck's winter cups is equally as beyond me as the college victimhood culture, but they seem cut from the same cloth.
How much of this is the media's fault by pushing a narrative? As an example, for the Starbuck's issue, I've seen a ton of headlines making fun of Christians for it, but I don't know anyone or have even read an article saying Starbuck's is waging a war against Christmas or Christians or anything else.
The same could be said about colleges. I was in undergrad <10 years ago, and I can't remember any of this (though I was in engineering). Has it really blown up like this? Is it the media pushing it and giving a huge megaphone to a minority of students? Or is it blowing up because they're giving these kids a megaphone, so people start thinking it is more and more reasonable?
