Sorry to disagree here but NEGRO/A means black and BLANCO/A means white. BTW, in some cultures ther N words is not used to refer to a race but to describe behavior.
Now, just how would you describe the "N" word as a behavior. From what I understand, that sure isn't done in the U.S.. Anyone that is heard using the "N" can be punished somewhat severely, other than Blacks to each other.
A word takes on the meaning of it use. That means that for the purposes of a majority Northern Hemisphere the N-word is an outdated term that is nothing more than a disgusting insult to a portion of our population. What it means in Spain, in Portugal, Franch, South America has zero bearing on its modern day first world use. Just stop saying it, OK not that hard!
Then, I wonder why Peter Renfro replied the way he did? Take a look at his reply that I called "excellent" above.
He is replying to your thread. Wife and I really don't want to know about other cultures. Even the city we live in isn't diverse at all.
The fact he is replying to mu COMMENT is his right / privilege...as is mine to opine on what I know. Ciao.
