Modern book "bans" in america usually refer to a school removing a book from the curriculum and taking it out of their school library based on some Christian lunatic complaining. The children are of course, still free to read the book on their own time.First is the ban done by the government? There's a difference between the government outright banning something in it's borders and from a Christian Library censoring certain books.
Second I don't agree with such a change of language in the book but if individual publishers want to republish the material (I think it's old enough to be republish this way no?) then they are free to do that. So long as it's made known that it's not an original copy and I my access to an original copy isn't stopped.
Third... it doesn't really apply to me anyways. I live in Canada. Last time I read Huckleberry Finn at the library in my school it had the word cool person. So did to kill a mockingbird... so did a bunch of other novels. Novels get challenged here all the time but normally the recommendation to the school boards is to keep the novel (actually of the times I've heard of these bans that's been the only recommendation...) and the school board complies.
One time in grade 10 English class while we were reading To Kill a Mockingbird I had to read the first part in the book that says 'cool person' I felt kinda weird saying it outloud in class so I said 'the big tall black person'. My teacher got so mad at me for changing the word. hahahaha
Here's a story about a recent "ban" of kurt vonegut's slaughterhouse five (by the way, it describes a very violent thing that happened in Dresden, maybe some people here approve?):
