There is an even deeper problem here, the "vanillisation" of the language.

The people who scream that words need to be buried to somehow hide the toxin soaked in them do not take into account that those who forget (or have never been told) of the past are doomed to relive it's excesses.

Explaining to children the absolute sadness of the racism of Huck Finn gives perspective that history books don't. Robinson Crusoe is another. The flipside of the coin is that some people who have been racially, socially or religiously suppressed can't let go of the horror, using it to justify their own excesses.

We're stuck on a Moibus treadmill.
