The US is so sensitive that they have their own Wiki page on it https://en.wikipedia.org/wiki/Controversies_about_the_word_"niggardly"
Mainly gaming/nerd instance for people who value free speech. Everyone is welcome.
Most niggers don't know of this word, and thus become very offended upon hearing it.
The irony is that the word actually perfectly describes most of them and as such they actually should be offended, but for a different reason. xD
