No need and I'm not sure about that Goldnumber-there's obviously plenty of smarter people around here than me with better and more informed posts on this forum I think but sometimes I can't resist responding to 1 or 2 posters when I think they display 'cherry picking', a 'one eyed' lack of objectivity and critical thinking, absence of reason, 'half truths', inconsistencies or just plain old 'codswallop'.
