Are people more easily offended these days?
To the basic question:
No. People are not more easily offended. Rather, people have a generally higher expectation of
being respected as a person (at least), and are more willing to
express how offended they are.
I also think that some people are unwilling to grant others the respect innately owed to a fellow human, and so we see many examples where matters of offense attract more prominent attention.
I brought in some extra tomatoes from my garden to share with coworkers. I placed them in the common area with a sign that said "free to a good home." A couple hours later, I can hear one of my coworkers on the phone talking about the tomatoes and complaining that she would have liked some but she came in late because of a morning dr. appointment. I hear here tell the person on the phone "Well, I guess DisneyBeagle doesn't care who she offends. She should have waited until everyone was at work before giving the tomatoes away."
Here we see a
counter-example: First-come, first-served is a very well-established principle of fairness in our culture. I could see offense being perceived if you shared tomatoes with everyone except for the (for example) Latinos. But laying them out for everyone, first-come, first-served, is in no way offensive in-fact.
My MIL is offended because her neighbor didn't wave when she drove by. I kindly said maybe the neighbor didn't see her, but nope MIL said "She is always doing stuff like that which offends me." Come to think of it, my MIL uses the "offended" word a lot.
This example is indeterminate. Your MIL could be right, or she could be fabricating the context of offense as you believe.
A friend is having a super small wedding (like 50 or less people) and she isn't able to invite every one that she would like to invite. One of my other friends mentioned the other day that she will be offended if she doesn't get an invitation. I can see that it might hurt her feelings, but I don't understand being offended.
No one is owed an invitation. That much is true. However, beyond that, if I have three friends, and I've always made them feel that I love them all equally, and then invite two of them, the third one does has reason to be offended.
Regarding the cases of fabrication of offense, discussed above: Do you think people haven't been doing that for centuries?
