It’s not an ignorance it is support for resistance. Israel collects all the taxes both in Israel and occupied West Bank. If I want to visit both parts of Jerusalem I have to land on Ben Gurion airport because it is the point of entering into Israel from outside for Jews and non Arabs. I don’t want to spend an euro cent on airport nor anywhere in Israel. Palestinians for instance are allowed to enter only via Alenby bridge checkpoint in Jordan valley controlled by occupation Israeli army.
