The white people are the descendants of Japheth. And the Bible says some pretty bad things about their race too, though it's all true also just like the pronouncements against Ham, the father of the blacks, are grim, but they are also true. Even the other Semites, the Asiatic races, became pagans and the Bible also tells very true things about their wicked races. The thing is is that shortly after the Flood all the races pretty much became evil pagans and the things they did, and still do, are quite evil. Is it racist to call them evil? Maybe it is, but that doesn't mean it's not true. The only racial exception is the Israelites as the man Israel worshipped the only true God in his time. Though in the course of history as the Bible relates the Israelites, and later the jews, would also betray God and reap the curses of his wrath, very often by mingling and mixing with the various races around them and adopting their wicked customs which made them forget about Lord God.
White people didn't become Christian until the days of the apostles of Lord Jesus. The first white man to become a Christian, if I remember correctly, is Cornelius, a centurion of Rome. The apostle Paul in the Bible is the foremost apostle to go out to the Gentiles, namely the whites, and he converted many of the white people early on and this is why Christianity would in later centuries rise in Europe and then subsequently in the isles of the sea that the sons of Japheth were promised to inherit.
