A newborn born to barbarians, if introduced into a civilized environment, will not be socially distinguishable from the rest of the people in that civilized environment. Transplant young children out of a savage environment and raise them in a civilized environment and they'll grow up to be civilized, provided that the people raising them are also civilized.
The problem is that many people are not civil, and they do not want or choose to become civilized. Some of this has to do with civilization never having been developed or introduced to an environment (look for example at how the Romans civilized northern Europe and later followed by the false form of Christianity called Catholicism; Germans and Gauls were more or less tribesmen in the woods).
The other part of this sadly has to do with female headed families en masse. A few widows is all a society should have. Instead, in the West, matriarchy was subsidized by the government, removing men from the household, which destroys civilization. Any statistic that can be compared between the fatherless children and those with fathers demonstrates that societies based upon matriarchy are destined to fail.
It's not a racial issue at all, but one of civilization and matriarchy. Racism is misplaced and a distraction in life that will destroy the life of the racist (just as feminism will destroy those who get entangled in it), if he or she doesn't figure it out early enough.

Salvation is the free gift of God simply for believing that Jesus is the Son of God, and it can't be lost; the only repentance necessary is the change of mind from unbelief to belief, because salvation is not about turning from sin because it is without works. Jesus, the Savior kept all the commandments in absolute perfection for us, ∴ salvation is without works, and He died for our sins, taking the eternal penalty for us.
