And Arthur Koestler, the Hungarian Jew who wrote the book "The Thirteenth Tribe" and Shlomo Sand, professor of history at Tel Aviv University, who wrote the book "The Invention of the Jewish People".
Shlomo Sand is a self-hating Jew who quit Israel's Communist party because it wasn't radically anti-Zionist enough for him. He is still an admitted Communist and a Marxist historian. He is also a crackpot. His answer to the genetic evidence is, essentially "Hitler would have liked the genetic evidence, so it must be wrong." The only people who take him seriously are Jew-haters.
Now, here's a question. Will you admit you are wrong? Or will you cast your oars with crackpots and Jew-haters over the considerable genetic, linguistic and historical evidence? And if you will, that pretty much says a lot about you.
