There wasn't much point in listing reasons why
The Handmaid's Tale might be banned, and there's REALLY no point listing reasons for the banning of
The Color Purple. We start with rape and incest, and move on to forced marriage and marital rape, lesbian desire, masturbation, lesbian sex, casting doubt on the bible and the masculinity of god, anti-colonialism, casting whitefolks in a bad light, more sex, implying that god likes sex (including lesbian sex)... you get the idea. If you're looking for something to ban, you can probably find something here to object to.
