I largely agree with your sentiment, but advise you not to worry too much on it. School, parents, social circles, they all contribute, and it's extremely variable.
IMO it's best to avoid 'oughts', because as kleinbl00 points out, the size of this problem of super-sensitive kids has been magnified for the very reason why this thread is growing so large. People get worked up about it. But, it's really not that big of a deal. Some university administrators will take 'safe place' to the extreme, but that always seems to be the case in cultural shifts.
I come from a family of educators. Most of your problems in the classroom are going to trump these.
