Is there an unwritten forum rule that conceding an argument is a sign of weakness? How about even acknowledging that your opponent in the debate has made a valid point? In the brief time that I've been here at USMB, I've observed that many many forum regulars seem to adhere to such a rule with unwavering servile obedience. I'm not going to single anyone out (that's for the flame zone), but on several occassions I've witnessed a person's entire position get completely dismantled and by all reasoned accounts wholly discredited. Yet they stubbornly and persistently deny that this is the case and continue to defend their failed argument with the ferocity of a caged, rabid badger. In my opinion, demonstrating an open-minded willingness to not only accept, but acknowledge, when one's argument has been bested, is more a sign of strength and confidence than it is weakness. But perhaps that's just me.
