It's actually kind of difficult to believe that you're really saying that--the PC police can't lock you up, can't send you to the gulag, but they can shame you on twitter!
That's no consequence. That's nothing.
As for Seinfeld not getting much of a laugh out of college kids anymore, I'd say he made the critical error of having dated, boring material. Humor's always changing, comics (unless they want to move into the corporate retreat humor circuit) got to keep up with the times.
Telling the audience they're in the wrong for not finding the old material funny? Now that's a good joke.
There is a lot out there you could use to learn more about this. Some starting points:

http://www.amazon.com/So-Youve-Been-Publicly-Shamed/dp/15944...
Which leads to job loss and career damage because you have a mob of 10,000 twats with nothing better to do than complain on Twitter to anyone who even so much as thinks of hiring your "racist ass" because you shared an article about the military armor having chinks in it [0]. Or do you think the Army was being racist? That's what people are terming as "PC" and "overly PC".

Comedy and tragedy go hand in hand. When someone is unable to make humor out of tragedy - you lose comedy. There is a reason that, outside of wordplay, most jokes play on disasters, stereotypes or outrageous scenarios. If you think you know a joke that isn't a play on words or isn't based on a stereotype, feel free to share it. I can't even think of one.
While I do have some respect for rakugo performances [1], it's not something a lot of people can get into. An entire comedy based on nothing but wordplay and puns only fits a niche audience. Maybe more people who do nothing but puns and dry humor should tell jokes at college campuses?
Joke: "I spilled some spot remover on my dog. Now he's gone."
Expected College Campus Reaction: "Animal abuse!!!"
Nevermind. Dry humor off limits too.
The college niche dislikes politically incorrect jokes. While colleges have always leaned pretty liberal, in recent years academia has gone absolutely crazy over gender/identity politics. Anyone who so much as laughs at a potentially-racist-joke gets shunned by their peers as a racist. So yes, it's fair to say "college kids are just too PC for the jokes" when they're still successful everywhere else and even among the same age range but with different, and less PC-extreme, political leanings.
