It is identical mankind. You're entering a cultural lens. You're talking about how they have a cultural that promotes a crime, such as Jihadism.

 Because it does. Then you have to know to racially profile. I have problems with white-people too. White-people have to pick up the ball & start running with it every time rain, snow, sleet, sunshine. Because then your children will have survivability. You invest in your children. It's a honor to have children, not a right. We don't have kids that get left on the street & shit. Every parent takes care of their kid. This goes with people with have foster children, too. We need these mentors out there. This is social, fraternal, & civil. 

Then we do it in a modern fashion. That's the moral fabric of society. Caucasians lived as native-americans or indigenous people to Europe. What if an Alien came & destroyed us? It's extraterrestrial life. It's intelligent enough to travel space. Or it can try. Maybe it'll be destroyed. Caucasians lived in town-community settings. That was the village. We are a hybrid. The entire human race. 

Settlers from around the World to Europe that integrated. In the primeval days, we migrated & settled in different regions & lands, & did not retain racial purity. Because a mutt is a mutt. No one practiced these observances of racial-purity. Because if we came from a Primate, we weren't different offspring then that genai & specai of Primate. This was an explicit teaching in Rome. The Germans, for example, were recorded as being as much of a mutt as a Roman. 

Because slaves were a trade in Ancient-Rome. Slaves were traded throughout Europe. Well, in Rome you could earn freedom by gladiator fighting, midwifing, marriage, education, trade, etc. I don't know of any other instances. Then you were made free & you became a naturalized citizen of Rome. We have no other records of such. The trade was primarily done in women & children. Then, yes, women & children slaves became a part of the Tribe, Clan, or Nation.
