in usa you should name african-american

in new zealand - black

in my country negro, bec black is impolite and offensive.

someone named the race - Negroid ...

 Correction:  Unless you have actually lived in Africa...then you are considered African American.  If you have lived in Mexico you are Mexican-American.  If you were born in America..you are just plain American.

If we were using the above logic raindrop...everyone in America would be European American accept for blacks & mexicans.

Is that really the case? I always thought that African-American was the PC term for all blacks.

 Correction!  You are wrong Teas - anyone with African ancestry is called African-American. This is because, unlike those of other nationalities born into the US, the original Africans were brought to the US against their will as slaves and, naturally, prefer to remember their origin.

Actually that´s not correct either, I have personally heard some black people object to the term of African-American based on the very fact that they personally have nothing to do with Africa (they weren´t born there, they have never even visited, etc). Whereas some use and prefer that term, others don´t care or are openly against it. So don´t assume you know what American blacks prefer if you want to become a spokesperson for them.

 My apologies - I should have realised that YOU were a better specialist on this subject - I was foolish enough to believe Martin Luther King´s definition

Further:  Just checked wikipedia, and think you should do the same (after all you are living in the US).  The term had been circulating since the 1950s and became prominent after a speach by the Rev. Jesse Jackson.   However, obviously YOU know better

 Maybe you should read what you link:

The term African American carries important political overtones. Earlier terms used to identify Americans of African ancestry were conferred upon the group by colonists and Americans of European ancestry. The terms were included in the wording of various laws and legal decisions which some thought were being used as tools of white supremacy and oppression.^[112] There developed among blacks in America a growing desire for a term of self-identification of their own choosing.

With the political consciousness that emerged from the political and social ferment of the late 1960s and early 1970s, blacks no longer approved of the term Negro. They believed it had suggestions of a moderate, accommodationist, even "Uncle Tom" connotation. In this period, a growing number of blacks in the United States, particularly African-American youth, celebrated their blackness and their historical and cultural ties with the African continent. The Black Power movement defiantly embraced Black as a group identifier. It was a term social leaders themselves had repudiated only two decades earlier, but they proclaimed, "Black is beautiful".

In this same period, a smaller number of people favored Afro-American. In the 1980s the term African American was advanced on the model of, for example, German American or Irish American to give descendents of American slaves and other American blacks who lived through the slavery-era a heritage and a cultural base.^[112] The term was popularized in black communities around the country via word of mouth and ultimately received mainstream use after Jesse Jackson publically used the term in front of a national audience, subsequently major media outlets adopted its use. Many blacks in America expressed a preference for the term, as it was formed in the same way as names for others of the many ethnic groups in the nation. Some argued further that, because of the historical circumstances surrounding the capture, enslavement and systematic attempts to de-Africanize blacks in the United States under chattel slavery, most African Americans are unable to trace their ancestry to a specific African nation; hence, the entire continent serves as a geographic marker.

For many, African American is more than a name expressive of cultural and historical roots. The term expresses pride in Africa and a sense of kinship and solidarity with others of the African diaspora—an embrace

This is from the same link you gave.

At least I can distinguish MLK from Jesse Jackson.

 Excuse me?  I can´t see your point   The only thing I see is that your definition was wrong

Where have I mixed up Jesse Jackson with MLK?

You said you were going by MLK´s definition, and the part I quoted shows that the term wasn´t even in circulation until 1980s, which is over a decade after his death. The bolding part got a bit mixed up and it´s too late for me to edit it since you quoted my post.

My post was based on feedback received from actual "African Americans" not from an article. Whereas most can prefer that term, don´t assume it´s "naturally" something that they would do, as many do not.

 As I said, I read in MLK´s biography that he used this term and that it had been around in the 1950s but became popular after Jesse Jackson´s speech much later.

The fact, whatever your friends wish to be personally called, is that African American and Black American are the US Government´s official terms of anyone of African origin or ancestry

I think you are just nit picking because you found that you are wrong

I´m not denying the use of the term. Like I said: "Whereas some use and prefer that term, others don´t care or are openly against it." The point being it is not natural for every black person to want to be called African American, as your post suggests. 

And I think my "friends" as you call it, have a better idea what they, as black people living in the USA would like to be called then you would.
