This is as it should be.

Refusing to acknowledge the existence of racist language and banning its usage in academic contexts leads to burying the past which serves no one.

In the proper historical context describing the mistreatment of blacks by white slave-owners in the U.S., what better typifies the hatred and disregard the slave-owners had for their slaves:

"N-Word"

or

"Nigger"?

Which word provides a better example of how blacks were viewed with prejudice, as property, and as an "other" by racist whites?

"N-Slur"

or

"Nigger"?

EDIT: It's interesting to note how you, /u/MagicCoat still censored yourself, even when describing the use of a slur in the proper historical context.

I bet it was simply automatic for you. That's exactly how language and thought policing works (through the development of self-censorship).

EDIT 2: Here is a very interesting video by Slavoj Žižek on the insidious nature of Politically Correct language, and how it is actually a more dangerous form of coercion than the outward application of force from a totalitarian oppressor in terms of controlling thought.

He argues that PC language and censorship is more insidious and dangerous than oppressive commands from above regarding acceptable language/thought, which would be backed by the threat of force, because it is easier to rebel against such an enemy, since they are so clearly identifiable as a dangerous oppressor.

Meanwhile, the imposition of politically correct language and the banning of certain words teaches the individual to censor themselves, and their feelings, to fall in line with those which are prescribed by a given society or movement.

And therefore, this is much more effective in controlling thought, and is much more difficult to rebel against.

Interestingly enough, this interpretation is fully in line with the views of other critical thinkers/post-structuralists such as Foucaut, who is mandatory reading in gender studies courses (see "The History of Sexuality), and also follows the same line of argument as Noam Chomsky's work in "Manufacturing Consent" and "Necessary Illusions" regarding how the media operates to manage popular thought on political issues.

And these guys are absolutely massively leftist (as am I).

But I think there is something fundamentally wrong with this new form of extreme-leftist based PC censorship.
