Why do some book critics find the outsiders too controversial?

Some book critics find "The Outsiders" controversial due to its portrayal of teenage violence, class struggle, and gang culture, which some argue may glamorize delinquency. The raw depiction of social issues, including poverty and familial conflict, can be unsettling for certain audiences, particularly in educational settings. Additionally, the book’s language and themes may challenge conventional norms, leading to debates about its appropriateness for young readers.
