Chances are I wouldn't sit and listen to anyone who was SCREAMING anything at me... regardless of the message. I don't mind points being stressed in a louder tone of voice-- but when they start screaming-- I generally tend to tune them out.
I think that comes from having to tune out kids screaming at each other sometimes... it's just an automatic response to screaming.
I'm not even going to bite on the "BDW" discussion....
