society isn't more sensitive, people are less respectful and caring of what they say.
40 yeas ago a kid wouldn't /dare/ mention some of the things I see kids say on a daily basis, and say myself. That's how it was, it wasn't any better or worse than society today, things were just different
Society changes, people change, but I wouldn't say we're any less sensitive, just less courteous of what we say to each other.
