Blame it on Tarantino. I was treated to Django Unchained by my daughter. Great film, lots of fun. Even though it is set prior to the Civil war, the use of the "n-word" has been touted in the media. It seems to be a fishing expedition to get a reaction. There is something to be said for being polite, an art lost on the internet it seems. One of the most offensive innovations by us humans is political correctness, conforming to a belief that language and practices which could offend political sensibilities.
This has become a strong-arm tactic used to shift the focus from points made to attacking the point-makers.
Always use the proper name for things. Fear of a name increases fear of the thing itself.~(Dumbledore via J.K. Rowling)
