There are very few reasons why self professed 'experts' come on a forum like this to 'calm the troops' and when unable to answer questions honestly, and to the satisfaction of all, dissappear.
People who are competent, honest and without secret adjendas have no problems answering questions and debating a topic honestly until all are satisfied and a resolution, which can be enthusiastically supported by the majority and (more or less) happily lived with by the remainder, is the result.
