Oh dear Richard I now think I understand what you mean. It sometimes takes a while for the old grey matter to compute. My post wasn't intended to be illogical and it didn't seem to be so as I was writing it - not to me anyway. Perhaps the problem is that so many people come here with different backgrounds, cultures and views it isn't surprising that we sometimes have a different perception of the same issue. Maybe that doesn't sound logical and you can tell me if you like, I don't mind that a bit. My Dad always used to tell me it's always worth hearing what people have to say, no matter who they are. Some of life's best treasures are difficult to see at first glance.
