What the hell you're talking about, all these terms are used in mass media and population in general, black and white. In official language Caucasian and African-American. Neither form is used as derogatory expression, and only such are avoided.
Can you post racial crime statistics to prove your point?
...and that's why America elected first black president. Do you want to see real racial changes in America watch movie "Battler".

Where were you hiding for all these years? Did you ever meet other races or ethnicities? Did you travel and talk to locals? Regardless, and I'm sorry to say that, but you are not the best observer. Your thoughts seem to resemble bad written racist book or a website of some sort of racist guru.
1. Did you ever read anything about Japanese extreme racist/nationalistic behaviour during WWII? Typical story of chosen people ruling inferior others.
2. China? Read this:

3. Arabs? Where should we start? So many stories so little time. Why don't you read yourself:

4. Indians? What about this little nugget freshly off the press:

So much for "Civilized" nations being non-racist.
I'm sure, with your anti-black philosofy you would blend well in India or China.
Racism and nationalism goes back few million years to simple hunter-gatherer tribes. To survive, to make one's group stronger, to unite a group against other groups, people of one group needed to start thinking about their special place on earth, special status, superiority, being chosen by god, protected by ancestor spirits. Not mentioning the fact that their were closely related to each other and looked almost identical, and were afraid of strangers who usually looked somewhat different. All these elements and others with positively uniting aspect, were beneficial to small groups, made them stronger and got encoded in our DNA . However the same elements are highly destructive to modern societies and the whole world. Nowadays these are the source of conflicts, wars, social injustice, nationalism, racism and any form of degrading anyone who is different than you.
The inner working of simple tribal instinct, to protect the tribe.
If you have any genetic knowledge you would know that you are already a nice mixture of Homo-Sapiens from Africa, Neanderthal, Near Easter Farmers, European Hunter Gatherers, North Asiatics, West Asiatics, Huns, plus many more admixtures with Jewish included. Post your DNA reading for a closer look.
