The self-aggrandizing ignorant is ignoring views. Even if one has a valid reason to move the attribute among the base relations, nothing requires the application to change.
If you are going to engage the self-aggrandizing ignorants, focus on the most relevant and substantive points. When they assume something false, simply point out how it is false and observe that the rest of their argument is unsound. Received on Thu Jun 29 2006 - 19:42:48 CEST
