But why?
There are 3 races on earth: europeoids, negroids and mongoloid
So, what is offensive to call white Europeans, black - negros, asians - mongols?
I don't see any offensive, honestly.
But calling all white Europeans is not correct as they might be from Americas, asia or any other continent. Mongols may be confused to nation of Mongolia, so Asian is more understandable. But negros is the most correct for calling black people, isn't it?
Same reason why people get fired for saying the word niggardly, even though it just means stingy. For ages, the term "Negro" was the accepted term for blacks, even by blacks. It's all stupid really;
Negro denotes "black" in Spanish and Portuguese, derived from the
Latin word
niger, meaning
black, which itself is probably from a
Proto-Indo-European root *nekw-, "to be dark", akin to
*nokw-, "night".
[4][5] "Negro" was also used of the peoples of West Africa in
old maps labelled
Negroland, an area stretching along the
Niger River.
Modern liberals taught us to be offended by everything, including mere words, then they invented the concepts of hate--speech and hate-crimes, though neither truly exist. It is the backward advancement of mankind to fear, hate or be offended by most everything under the term "progressivism."
