I disagree, I don’t think children are more sensitive today I think children are exposed to more today than in earlier generations and people in general are so much more rude and judgmental.
In earlier generations Parents and adults were much more careful to guard “adult” information from children such as financial issues, illness, death, shalom bayis issues, community issues, lashon horah, etc. Today everything is an open book, especially in school if parents have not paid up tuition, kids are kicked out for all to see. Loshan Horah has run rampant, even a 5 year old knows whats happening up the block. Neither parents nor teachers/Rebbeim are teaching mussar appropriately and that goes for etiquette and manners. No one cares anymore how the other person feels, everyone is so into themselves and that goes for the younger generation as well. When was the last time a kid got up for you and gave you their seat? Have you been to a kiddush or a bris lately? Have you noticed how parents seat their kids down at the table as if the simcha was a party prepared for their children even though there are invited adult guests left standing balancing their plates in their hands?
Is it any wonder why kids get hurt? Does anyone really care that they get hurt? Is anyone taking responsibility for the fact that so many kids are getting hurt? Is a child being sensitive because s/he is hurt they were thrown out of school with no where to go as if they were a piece of garbage? Why hasn’t any adults taken responsibility for all the children that went off the derech because of this one issue? Could they not have been saved? Were all these kids being too sensitive? Do you have any clue how many of these kids, who were really, really basically good kids went on to do heavy drugs because they were kicked out?
Kids are NOT too sensitive today, WE the adults are TOO judgmental and rude.
