* Riverwalk's* question 'where have you been?' is a very interesting one and very pertinent to this issue.
i do think some people who have not worked in certain jobs, environments, been out in the world much, read certain books, etc. may well have missed out on an understanding of what is acceotable and what isn't. This isn't a reflection on them as such, it's more a case of 'you don't know what it is you don't know'.
Certainly since I retired I rely on my children, TV, radio, reading and even GN more and more to keep me up to date with certain issues. This thread has raised an issue that some people were unaware of. Well that's progress.
