Raedwulf, Michael and I differ on this particular subject, but nonetheless I feel I must object to your choice of language and vituperative attack on him in your last post. 'F*** you, you narrow-minded, patronising prig...' is not the way to disagree with someone. It's abusive and unpleasant, and completely uncalled-for, as was your dismissal of my argument as 'absolute bollocks'. I don't think Mudcat is the place for this sort of invective.
