You are totally deluded claiming that,"the only semites in Israel and Palestine are the Palestinians and the Mizrahi jews",
Ashkenazi Jews are regarded by Jews as being as much Jewish as Sephardi and Mizrahi Jews, as all are Jews either by descent or conversion.
Your idea that Ashkenazis aren't Jews genetically is also absurd, as they descend from a small group of Jews 'bottle-necked' in Europe around 700 years ago.
Jews can be of any skin, hair and eye colour, white, brown, red-haired blond or black, with blue green or brown eyes, and they don't have to be descended from a Jewish mother to be a Jew either, as many Jewish males took on non-Jewish wives in both Biblical times and later, who converted to Judaism.
You could try reading this article on Jewish DNA and open your mind a bit.
It blows holes out of the German origins theory of Ashkenazi Jews.

Another thing, Semites include Jews, genetically and their language is also called Semitic, but as with all lineages, admixture with other lineages occur to some degree or other.
Judaism is a religion, not a race, and not all Israelis are Jewish, and many don't practice Judaism at all.
You too can become a Jew if you so sincerely wish.
But the rabbi you go to see for studies and instruction in Judaism will do his best to dissuade you from converting.
