Post DNA genetics has long since shown that the notion that Homo Sapiens is divided into races is false.    So declaring that races exist is indeed racist - and ignorant.
Scientific method does enable us to say beyond doubt that a theory is 'true' in all circumstances but it can and often does disprove theories; that is how science moves forward.   That is how it is with 'race'.
		
		
	 
 
"The Inequality Taboo," by Charles Murray, 
Commentary, September 2005
 
The Harvard geneticist Richard Lewontin originated the idea of race as a social construct in 1972, arguing that the genetic differences across races were so trivial that no scientist working exclusively with genetic data would sort people into blacks, whites, or Asians. In his words, “racial classification is now seen to be of virtually no genetic or taxonomic significance.” (25)
Lewontin’s position, which quickly became a tenet of political correctness, carried with it a potential means of being falsified. If he was correct, then a statistical analysis of genetic markers would not produce clusters corresponding to common racial labels.
In the last few years, that test has become feasible, and now we know that Lewontin was wrong. (26) Several analyses have confirmed the genetic reality of group identities going under the label of race or ethnicity. (27) In the most recent, published this year, all but five of the 3,636 subjects fell into the cluster of genetic markers corresponding to their self-identified ethnic group. (28) When a statistical procedure, blind to physical characteristics and working exclusively with genetic information, classifies 99.9 percent of the individuals in a large sample in the same way they classify themselves, it is hard to argue that race is imaginary.

---------
 
A person's race can usually be determined by appearance and always by DNA analysis. The different races differ significantly in average qualities necessary for the creation and maintenance of successful societies. These are intelligence, obedience to the law, and monogamy. These differences are the result of evolving for thousands of years in response to different population pressures. 
 
Agriculture requires the willingness to defer gratification and the ability to plan ahead. Living in a cold climate requires the ability to build warm clothes and habitations for the winter months. Food must be stored for the winter months.
 
Civilization exerts more evolutionary pressure on superior intelligence. Intelligent men usually become more prosperous than unintelligent men. During most of history they had more children who survived to adulthood. 
 
I define a civilization as a city based culture where the government has the effective monopoly on the legitimate use of violence. During most of history in civilizations criminals were killed at the scene of the crime, they died in custody, or they were executed. The few children some had rarely lived to adulthood. In a civilization the military becomes an occupational specialty. Most men never participate in war. 
 
Tribes exist where the government is weak, ineffective, or does not exist. In a tribal society all men participate in war. The best warriors have more than one wife, and more sons who inherit their lethal inclinations and aptitudes. While a civilization selects genetically against physical aggression, a tribal society selects for it. 
 
These factors explain why races that have practiced agriculture and civilization the longest have higher IQ averages and lower crime rates than races that have been recently introduced. The more civilized races can easily be identified by lighter skin color. This is because they evolved in northern climates where rickets was more of a threat than skin cancer.
