I need the participant I am "attacking" to stop being patronising and condescending (which is precisely his way of attacking). He has a history of this in other threads. He is far from being the guru of all things he seems to profess to be. I tend to be fairly direct when I don't like what's going on. If that's a fault, well that's me. I would heartily welcome a return to a straightforward exchange of points. Thank you.
