Walking around in slippers and napping wherever is a consequence of freedom from social conventions, or at least an environment where social conventions are anomalous and rapidly changing. So is promiscuity, once called free love. These are things that universities have always been havens for. Others things (puppy rooms) are experimental, also an artifact of a nonconformist and liberal environment.
Students and academics have more license to be quirky and eccentric than lawyers and soccer moms. That's a good thing.
I also cringe when I here about PC student audiences that can't tolerate stand up comedy. It all feels like a part of the recreational righteous rage, liking to be right and pointing at the kid that said the C-word.
OTOH, it's also a side effect of effective social movements that take place at universities. If I look back at social movements that universities played major roles in, I don't think they've been bad. Attitudes towards queers and trannies have changed so much in my lifetime. Amazingly. There is tremendous support and solidarity from the public. It's a breathtaking rise in collective conscience. If I'm going to be yelled at by 19 year olds for saying "tranny" but we get to a point where transexuals can work and live normally, homosexuals can have families…. I'll take it.
Part of the way that is achieved intolerance towards "assholes," homophobes, xenophobes, sexists. Students, being young and insufferable spray that all around. Long term though, it sticks mostly where it should.
But yea, I agree. Young people are annoying.
