What do we know about Jesus, if we go by the Bible?
we know he was a Semitic Israelite, a Jew and probably was a Rabbi, right?

Actually no we don't.
Since there is no proof who Jesus father was, his father may not have been Jewish, and could possibly have been Roman, a Greek or a European trader and therefore white.
Since Judaism/Israelite heritage was passed down through the male line in those days, not the female as it is has since the 12th century; Jesus could quite possibly have been White, gentile.
Even if Jesus' father was God as suggested in the Gospel of Luke, the god of the Jews was not an Israelite, nor was he descended from Sarah, therefore he was not Jewish, so neither was his son.
Lots of history from the time suggests that far from being a Jew, Jesus was in fact an heretical Nazori priest of the Mandaean cult contemporarily headed by John the Baptist and Dositheus his immediate successor who were for all intents and purposes followers of Enoch's teachings, not Abraham's.
