Iains, I have appreciated many of your posts on this subject. You have provided many thoughtful, incisive and meaningful contributions and I'm sure many of us on here have learnt from you posts.

However you do not stand any chance at all of educating some people so for the sake of your sanity don't jump through any more hoops it is a complete waste of time. I'm sure you have noticed that I, and some others, ignore the idiot, some would say troll.
