Dear Doctor Sb,
Unlike truth and absolute knowledge opinions vary. That creates a natural room for exchange of views based on personal perspective. But it would be rigid to accept an opinion as the only given opinion without deliberation. Cross pollination of differing views based on conscience fertiles our mind. Judgments are weighed upon each others reflections; right opinions prevail, wrong ones change some time silently. Such deliberations however in no way mean to demean the respect of each other. Our Prof. M. Rafi is among the finest minds always enriching the Forum.
