Regarding comments I'm seeing here saying Israel is an apartheid state or that Israel is racist or that Israel the concept of a Jewish state is disgusting:
Israel is the size of New Jersey. It is the only state on earth there is a Jewish majority. There are many places on earth where there is a Christian majority, and there are many places on earth where there is a Muslim majority.
The Jewish people represent a tiny percent of the world's population in part because they have been expelled from their homes throughout history, and the majority of them were killed in the 1940s.
Why does it matter to have a Jewish state? Because it is a measure of defense against what has happened countless times throughout history.
The problem with a Jewish state in Israel:
Obviously, Israel, and especially Jerusalem, is a holy state for multiple groups. Those groups have a justifiable interest in living in Israel and enjoying the same rights as Israeli citizens. The issue is that if citizenship is freely given, Jews become the minority in Israel and it is no longer a Jewish state.
If you say "Good," to that, that is your opinion, and I will add that there are Jewish Israelis who agree with you. There is debate in Israel and abroad whether Israel should be a Jewish state of a state of the Jews. In the latter, there is more room for Palestinians--as it stands, this is not the policy of the current coalition.
Israel was not built by its founders to be a melting pot, it was built as a home for displaced Jewish people. It was not built to be a place of equality, and unfortunately, by its nature it cannot be one and continue to serve its purpose. If you think that purpose is racist, you are entitled to that opinion, but there are many who believe what Jews have faced throughout history justify a Jewish homeland, and it is very difficult to have a Jewish homeland, at least in Israel, without maintaining a Jewish majority.
