Roger, being an advocate certainly does not make one wrong. But the role of an advocate is to persuade and motivate action. The role of an intelligence agent, a scientist, and a reporter is inform.
I don't know what you include or not in "mainstream media." Most reporters and editors strive to report the facts as fairly and realistically as they can. Editorialist and columnists opine. In many publications, these distinctions are respected. Some less so. I do not consider Fox News or MSNBC to be journalistic ventures.
After my academic training in math, physics, and other physical and social sciences, I spent most of my professional career as an analyst, evaluator, planner, and strategy consultant, as well as a sometimes journalist, author, and editor -- with occasional stints as a teacher and lecturer.
My friend Adam Urbanski, longtime teacher and union president, came to America as an immigrant from Communist Poland. He told a seminar I invited him to speak at several years ago that most Americans do not understand what leadership is. They think, he said, that a leader is one who gets people to do what he wants them to do. A real leader though, Urbanski explained, is one who helps people make informed choices.
I agree. At least, that is what I've tried to do in my work.
BTW, I do not believe I have advocated on behalf of nuclear energy, as you put it. I have pointed out, as others have, that nuclear power -- like most things -- has benefits, costs, risks, advantages, and disadvantages. Also it is not just one thing, but a category that includes a variety of different technologies and designs. As such, it is an option that deserves to be considered alongside others and evaluated for its merits and liabilities relative to other alternatives. As a strategist, I've suggested that for those concerned about AGW, it seems foolish to reflexively reject all nuclear options out of hand without assessing alternatives or having other effective solutions available. I also have criticized TBI and others who advocate nuclear power wholeheartedly for focusing on the minimal mortality from nuclear accidents while ignoring the reality of the 'dread' factor in social psychology. And I have often pointed out that the light water nuclear reactor design originally developed for submarines was a poor choice for civilian power production that was promulgated more for political purposes than for technical merit.
That is analysis, not advocacy.
