Talbot, I don't ignore your question because I am 'frightened' or 'cowardly', I ignore them because I am sick of you following me round thread to thread, section to section, looking for an argument, preferably personal and off-topic, so I am ignoring you in the fervent hope that you will find someone else to play your tedious games,with, and I can get on with exchanging views and information with people who want to do that, not you who wants to fight all day every day.
I don;t want to answer your questions, I don't want to debate with you, I'd prefer it if you just ignored me.
