I always found gender-advertising a little off-putting. Even as a child I was offended by commercials where there were only girls playing "house" and only boys playing with cars on a racetrack. Our society is set up from word go as a binary gender system and seems very inflexible even to this day with advertising. It's a system that is constantly perpetuated by itself.
And the sports/beer/cars/"real man" stuff is just nauseating. How many men out there feel they can't like certain things just because they feel their peers would call them a "->-bleeped-<-" if they did? Why, in the year 2010 are people still being judged as less of a man for simply liking certain things? Ugh.
