Response to Tyler T: Gender Discrimination in Advertisements

As Tyler  noted there is a battle of the sexes going on in advertisements.   This clip of different ads has a great variety of ads that are blatantly screaming to men, "your not a man unless you do manly things..." and manly things do not include diet drinks.  Why would a man need a died drink? Is it because a diet drink has taken all of the calories out, there for not real or acceptable for a "real man" to drink?  

Does ten calories in a drink make it that much more of a manly drink?
