Here's one case of the banning:
$1:
A Judson, Tex., school superintendent banned the novel from an advanced placement English curriculum after a parent complained that it was sexually explicit and offensive to Christians. In doing so, the superintendent overruled the recommendation by a committee of teachers, students, and parents. The committee appealed the decision to the school board, which overruled the superintendent in 2006.
I saw
another one where a kid was complaining the book had been banned from his library for a scene of violent sex against a woman and misogyny.
Funny if true, because it would be a case of the side outraged by the banning being responsible for it. You know like if the SJWs were to complain about the time they banned Huckleberry Finn when it was them who banned it. Actually I'm not sure, did they succeed? I know they tried.
But book banning needs to be made public and debated no matter who's doing it. Even when the cases are rare, scattered and just involve things like school libraries.
