I've said it many times and I'll repeat once more, just for you. The open-minded scientist is not morally obliged to listen to the ravings of every nutter on the street corner. That is not what being open-minded involves. If we did, we'd get nothing done. Furthermore, we would be encouraging nutters to think more highly of themselves and their ideas than they deserve. Once one has read up the idea, and read the critiques of it, one is entitled to form an opinion. Thereafter, there is only a moral obligation to give the same idea more attention if new evidence is put forward that could be expected to change one's orginal assessment. Have a nice day.
