Stereotypes in TV show

Stereotypes are found in so many fields, even in popular tv shows. One of the popular television show these days is Glee, and I enjoy watching the shows because they have a great music. A lot of people love the shows, but they include some stereotypes. There are some completely different characters in the Glee, and they can be subject to stereotypes. First of all, I do not why many shows describe blond girls or cheerleaders as bitchy. A blonde girl cheerleader, in Glee, is shows to be a smart character, but is actually evil. Moreover, one of another blonde girl is described as dumb. Many shows  use this stereotypes, though. Next, African American girl is described as lazy and food obsessed. On the show, one of other character says, "Overweight, African-American diva,"to African American girl. In addition, Glee uses Asian stereotypes, "Asian F". When Chinese American character, Chang gets A- on his chemistry test, her father force him to quit Glee. His father puts him on pressure to get straight, and says A- is horrible grade. This is a typical Asian stereotypes. I am Asian, but I don't care about those types of stereotypes because it is just an image. However, the use of stereotypes in popular show like Glee, would cause not to stop having stereotypes in the U.S. and might hurt someone..
