At first, the kids at school liked Stargirl and were ok with her being so different. Soon, it was because of her that everyone started showing up at football games (or basketball, I forget exactly what sport it was). Then, they started getting super competitive, and Stargirl liked to cheer for the other team when they scored, so they got mad at her.
Pretty soon, the whole school started shunning her, except Leo of course. And because Leo liked her, and they were always hanging out together, they eventually started ignoring Leo too.
Stargirl is my favorite book, so I felt inclined to answer this one, lol. Hope this helps you, baii <33
