Wow, you are fluent in French aren´t you?

yeah, I was wondering if it wasn´t a faux-pas but I wasn´t sure what synonym to use to cover non-white population

 Nope!

 The current popular term is "person or persons of color...woman of color....man of color....

This expression is so typically ´PC´ .   I am sure most ´women/men of colour´ don´t feel the need to refer to themselves as such.  Presumably in this climate I should refer to my self as a ´woman of no colour´?  So going back to the main post in this subject I would like to declare that I´m proud to be a straight woman of no colour - is that allowed? 

 Yes, I agree....it´s sooooooooo PC....but that is the way it is.  People actually do call themselves  "a person of color"....BTW....I´ve noticed the definition of just who is "white" has narrowed greatly in the last 20 years. 

As regards to your statement...for me I´m trying to be human.....

Many in the US are registered colored on their birth certificates.  Then there was a time when people where just "black" regardless of what ever other blood they had.  I knew a woman who was Amerindian, Chinese, Filipina, Arab and White.  She was incredibly exotic looking, but at that time, she was just "Black".  A new term for multiracial/ethnic people is in the works....but it hasn´t stabilized yet. 

It might interest you to know that the NAACP stands for National Association for the Advancement of Colored People.

Turkish word used for black people is "zenci" a derivative of zanci from the Persian language. A quick browse about the origins of this word produces the interesting etymology of the town of Zanzibar.  Zanci originally means rusty.

Interestingly Turks had not had contact with any black people before the 11th century. Therefore all the vocabulary describing them was borrowed from other cultures.  People used the word zenci for ages and then began using siyah or siyahi following the anti racist trend in the US.  The word zenci is now kind of avoided in formal situations.

I have always found the American people to be  extra sensitive about skin color.  Although people in Turkey can´t be called homogeneous racially, there are just a couple words used to describe skin color like esmer and acik tenli (dark and light skinned) or sarýþýn (blonde). 

I know there are many races living in the country but in my opinion race must not be used as part of one´s identity in the US (and any other place).  I mean, we shouldn´t call people as that black lady over there, that white boy etc.  If we don´t know their names, we must call them just a man or a woman. In a newspaper article, unless it is really needed, we musn´t introduce people as black, yellow or white; just their names and surnames. This way we can clean racial awareness in society by educating children accordingly.

 I agree, that is one of the things that I love about Turkish culture.  To define people by their color, ethnicity,  gender preference (LGBT is controversial in more ways than one) is in my opinion silly impractical, inefficient and uncouth. 

 It is has saddened me greatly when I see people who come here from other countries get defined with these narrow categories.  I´ve seen some Turks and in particular some of the darker Turks, and people from other countries become aware of their and other people´s color. 

Actually there is a lot of baggage associated with the "black" designation, and the adoption of it by "black" people.  It was sort of a protest, or play on words, so to speak.  It comes from the "one drop" rule.  That was if a person had one drop of black blood, they had different rights.

As  Langston Hughes wrote, "You see, unfortunately, I am not black. There are lots of different kinds of blood in our family. But here in the United States, the word ´Negro´ is used to mean anyone who has any Negro blood at all in his veins. In Africa, the word is more pure. It means all Negro, therefore black. I am brown."

The one-drop rule was a tactic in the U.S. South that codified and strengthened segregation and the disfranchisement of most blacks and many poor whites from 1890-1910. After Supreme Court decisions in Plessy v. Ferguson and related matters, White-dominated legislatures felt free to enact Jim Crow laws segregating Blacks in public places and accommodations, and passed other restrictive legislation. Legislatures sought to prevent interracial relationships to keep the white race "pure", long after slaveholders and overseers took advantage of enslaved women and produced the many mixed-race children."

It was only as recent as 1967 antimiscegenation laws were repealed in all parts of the USA.

No pun intended but.... why can one call people as ´the man with glasses´, ´the bald man´, ´that fat lady´, ´the blonde overthere´ but not ´the black lady over there´? Sometimes it´s just easy to make clear who you (general)  mean, especially when pointing at a group or crowd. I think it´s more in the minds of people hearing these words calling it racist than it´s meant by the speaker.

I have to agree with you.  If you are pointing out someone in a crowd (and don´t forget it´s rude to point ) then it makes sense to use their most obvious characteristic and if this is their colour then it makes sense.   What I think is most ridiculous is the trend to consider it wrong to use expressions like ´black sheep´ or even ´blackball´
