While I don't have any respect for the very concept of "banning" words, not least because it cannot actually be done, I do wholeheartedly agree with every point on the Lake Superior list. Especially that "the American People" one; anytime you hear someone say that, they're dropping some grade A bullshit in the service of one or another much more specific group of people.
On the subject of banning: I don't know exactly where it is that the central story originates from, but there's quite a few school districts in the United States that ban any material that includes the word "nigger" from being present in their classrooms, libraries, and otherwise. The American classic Huckleberry Finn, as a contextual novel about slavery in antebellum Missouri, has quite a few instances of said word. So now there's a movement afoot to print new, censored editions of Mark Twain's novels, so they can be read in classrooms again, which is an awkward turn of events any way you slice it.
I'm pretty sure it's not a universal issue, because I know I read Huck Finn in highschool, but it's still a philosophical moment in the theory of education.
