All,
I do apologise, but having thought about this really hard I have decided to delete my earlier post. I still believe that there is an element of truth in it, but I also believe that the post has the potential to cause offence to some and even possibly affect the good name of PPRuNe; and I would not want that to happen. Therefore I have removed it.
Bob V, thanks for your comment and apologies that my post is now removed.
