My parents weren't always very attentive. We were to be NOT seen nor heard most of the time. "just go out and play!" was a common phrase in my household. I think that's a big difference. Today's version of "just go out and play" is "here's an iPad, leave me be."
Being offended has been around forever, btw. If you disagree, it's probably because you're a straight white male.
In all seriousness, I remember being offended all of the time when kids would pick on me in middle school. That usually ended with a punch to their face. I was raised kind of wild. I also felt offended for the queer kids who were beat on and picked on mercilessly. If you can't tell, we had a lot of ghetto kids in my schools, which is likely different than what you experienced, and definitely different than what my kids will experience.
