Thank heavens for that. Now, can I ask a possibly naive question? I am still not sure why explaining your reasoning to arrive at an opinion is important. When I vote I am not asked why I voted that way. When I go to the pub to indulge in some quite intense debates I am not questioned about my motives. I have said I am not interested in getting someone who obviously disagrees with me on my side. So why does it seem important to some? Lighter, you seem to understand it. Can you explain?
