The movie Mean Girls (2004), is a perfect example, in my opinion, of why it is so important and healthy for us to ditch the labels in our own lives. From the beginning of the movie, Cady Heron (Lindsay Lohan) is plagued with the labeling disease after being introduced to labeling by her new friends. Even though she was home schooled and wasn't quite used to many of the social norms among her age group, she learned quickly to label various groups of her peers on her high school campus (starting with her own group of friends) and especially her fake friends, "the plastics."
Like my high school, there were all these groups that primarily associated with members of their own group or click: the jocks, the nerds, the cook kids, the drama club, band geeks, etc. And while I was able to to successfully avoid any backlash as I moved amongst the various groups in my high school, mostly because I wasn't that popular; for Cady, it wasn't so easy as she had a different agenda from the start. Her main priority was to become one of "the plastics" in an effort to take down the leader, Regina George (Rachel McAdams) in an attempt at revenge for one of her new friends, Janis Ian (Lizzy Caplan). The only problem was that instead of continuing to influence them for the better, as she initially did with her fresh views of life since she spent much of her youth growing up in Africa, she allowed some of their not-so-nice ways to influence her behavior, which included making fun of members of the other groups around school...people whom she didn't even know.
In the end, Cady realized the damage that she and her classmates were inflicting on each other by labeling/judging and that doing so was particularly devastating because, as you may know, even if you are interested in a particular thing, that one thing does not and should not define you as a person. You see, what I know for sure is that we are all complex beings and labeling is often inaccurate and limiting with respect to describing who we are and want to be.
