The flag of Israel is the most controversial flag in the world. The Muslim community is very opposed to this flag. According to the Israeli Constitution, Israel is for only the Jewish people. The flag has the symbol of Judaism on it. The state of Israel itself is questionable, so any symbol of Israel will be controversial.
The banner of Israel includes the Star of David on it. Obviously, the Muslim populace is exceptionally restricted to this banner. In the Israeli Constitution, it expresses that "The State of Israel is a Jewish State and the National Home of the Jewish People, wherein the Jewish People satisfies its longing for self-assurance as per its recorded and social legacy". It obviously expresses that Israel is for the Jewish individuals, and the Jewish individuals ONLY. The banner is an augmentation of that, as it flies the image of Judaism. The province of Israel all by itself is questionable, so any image of Israel will be dubious.
