I think that this gets massively exaggerated. But lets take a look closer look.
-The people who complain about everyone being offended over things get offended by things that are offensive to them. There are "tough, Anti PC guys" that will scoff at 2 guys holding hands walking down the street and want laws made to make sure they can't live their lives happily."
-There are people who get offended over something like Pokemon Go
-Historically people were killed because others were offended by them and their lifestyle choices
-There are people who will get offended over Harriet Tubman on the new 20. And so on and so on.
-Trump complains out things being too PC all the time and how easily offended the liberals get. That guy gets offended more than any other presidential candidate in a long time. But people think that because he complains about PC that he's tough.
But people seem to only believe that the people getting offended over things are hipsters with bernie bumper stickers smoking american spirits. People like you are part of the problem. You exaggerate. Then you tell someone else "HEY DEEZ GUIZ WANNA BAN BLACK FRIDAY" and people start talking about it online. And then it spreads to "OMFG WE HAVE TO BAN BLACK FRIDAY NOW CUZ OF THIS WAVE OF PCNESS". And that's kind of a pussy thing. Just like the Hillary Clinton witch hunt. People are offended when she does something, ignores it when others do the same thing.
Yes, there are pussies out there. But they aren't tied to a generation. Or a lifestyle.
