They are correct that 90% of them have no white heritage. However about 9% of them come from Edom and Esau. Esau was white, but he married Canaanites. They also started out white as children of incest. However due to their sexual practices they quickly lost their heritage. So they look white, because they like to intermarry to destroy white heritage, but they are not white. They are a very mixed group. The modern day Jews are not, and have never been, God's Israel people.
