The Africans have a whole enormous continent of their own, a continent rich in natural resources and opportunity. The Israelis only have a tiny strip of barren desert land a few miles wide. There is no cultural connection, or racial, or religious connection, or historical connection between Africa and Israel.
Essentially African parasites are just looking for another host which will allow them to suck its blood. The history of African migrants show that they bring nothing to the host's table, but violence, crime, topped with intractable social, and economic burdens.
"Genetic tests carried out by British scientists have revealed that many of the Lemba tribesmen in southern Africa have Jewish origins, according to a report by the BBC. The Lemba, a tribe of 70,000 to 80,000 members who live in central Zimbabwe and northern South Africa, have customs which are similar to Jewish ones: Lemba refrain from eating pork or other foods forbidden by the Torah, or forbidden combinations of permitted foods, wear yarmulke-like skull caps, conduct ritual animal slaughter, have a holy day once a week, and even put a Star of David on their gravestones. According to their oral tradition, the Lemba are descended from seven Jewish men who left Israel 2,500 years ago and married African women. The Lemba prefer their children to marry other Lembas, and marriage to non-Lembas is being discouraged."
