The novel implies that Julian is the way he is (rude, exclusionary, and mean) because his parents are that way—specifically his mom. After Jack punches Julian, Julian's mom is fine with Jack returning to school, but she demonstrates shocking closed-mindedness when she suggests that it's too much to ask for her son to be nice to August. She even tries to get August removed from Beecher Prep altogether, though she eventually ends up pulling Julian out of school instead. She also unabashedly edits the fifth grade class photo to get rid of August and distributes the photo to several other parents.
