Books provide their readers with a variety of different experiences, vocabulary, and perspectives to learn from and adapt in to their daily lives to better themselves. Banning any sort of book is banning a person’s right to educate themselves and broaden their perspective, so it should not be allowed.
(This could depend on what your points would be in the argument. This thesis is based off the argument that books give readers lots of different knowledge and experience that they might not have known about otherwise. Hope this helped!)
