Infoboxes have their limitations.  This is one of them.  Have another look at my post to the talk page; your input appears to be sincere yet also has missed nearly all of the referenced points I was making:
In the post-Reconstruction, pre-WWI United States, the "N-word" was far less transgressive than it is today.
That particular word has undergone such a dramatic reduction in social acceptability that it must be presented within context, if at all.
This isn't because of the word's offensiveness to modern sensibilities per se; it's because twenty-first century readers would not understand its use as a nickname for a white man and would have no point of reference for how it would become a badge of honor to him.  Context must be provided or else it is shocking and misleading rather than informative.
It may not be possible or necessary to contextualize that moniker adequately within the bounds of WP:NPOV, specifically WP:UNDUE.  The nickname is a minor part of Pershing's life and career.  A similar nickname in Irving Berlin's biographical background has more than twice the returns on Google Books, yet is not mentioned in his Wikipedia biography.
