Re: Of course! I see it all now.
"Why haven't we noticed this before? Why does it take a foreign chap to show us the things we've hidden from ourselves."
Sadly, that is sometimes what's needed. Of course, you already have a well tuned defence mechanism that tells you that any such criticism is wrong, and/or irrelevant.
It's the same in most countries, the blinkers are on.
It's useful to be aware of this fact though.
