When did people become so sensitive?

I can't post a question without someone reporting it even though it clearly doesn't violate any guidelines. This seems systemic or our society in general. We have become the litigation generation. We don't seem to want to take responsibility for our own feelings or actions. If we don't agree with something or someone we immediately look for retribution, we don't acknowledge our own deficiencies. When did we become a society of soft, hyper-sensitive individuals? What's behind this regression- is it parenting or has our culture changed? What are your thoughts on this behavior?
