Did the author achieve his purpose?

Yes, I think the author achieved his purpose. His purpose was to send a message to the people who are perceived as different. He thought that these “unique” should also be given equal attention. The school in the book represents the society. While Stargirl, represents the “unique”people. He thinks that the people who fit in the society should understand and accept  differencesbecause It will be very hard for aperson to change his or her natural self.

Another message is to accept one’s self. You have to learn to accept who you are. You don’t have to adjust to the society and act like they do. Just be yourself. In the story, Stargirl wanted to act like the rest of the students in their school. She did this because Leo Borlock, her boyfriend, wanted her to change. However, Jerry Spinelli wanted to tell the readers to accept peoplefor who and what they are. Leo Borlock liked Stargirl because she was different and not for who she really is. He liked Stargirl because she changed her self for a while. Nevertheless, 

It was also mentioned that even though Stargirl changed herself for the students to like her, the other students in MICA  still continued to shun her. Her only friend Dori Dilson did not like the changes that Stargirl did to herself. Even though she hated Stargirl’s change, she was a loyal friend to Stargirl. Dori accepted Stargirl for who she is.

 If you are a different person you have to accept the fact that you will really be bullied by other people, but those things should be forgotten and that you should let it pass.

People who were perceived as different have to consider the fact that there is a possibility of being bullied because of their uniqueness.  The bullies will have to face some consequences for their actions. An example would be, they could be put to detention or they could also be kicked out of school for bullying.
