KenV - I too am getting tired of the sneeringly condescending and abusively-worded posts directed towards you. I suspect I am not alone in remaining keen to hear your authoritative contributions despite the witch-hunting efforts of others who, seemingly lacking your background and currency, resentfully quibble everything you say and attempt to trip you up in petty fits of pique.
If your detractors acted more civilly, i might give them more credence. However, please remember what I said about not stooping to their level. You are as entitled to air your views as anyone else and I detest group bullying, even on the internet.
