no u r almost completely wrong
Zionism set as its goal the transformation of Jews into a race/nation hence why in Israel you can be Jewish under nationality, because being Jewish is a nationality whilst leaving religion completely blank.
Yes outside Israel to a lesser extent u can be a Jew only by religion but even there Jewish identity is being transformed.
Semites are a linguistic category they are not an ethnic group. That was the mistaken belief of Wilhelm Marr who coined the term. Marr was an out and out racist.
