I am not Israeli, so this has absolutely nothing to do with what I just said and your response completely ignores my point.
However, as you made it, Israel is a multicultural, democratic society but unfortunately unlike Singapore it has always had people on all sides trying to wipe it from existence. Although that is thankfully lessening as it's neighbours move forwards.
Those people wanted to do wipe it from existence because it was Jewish. Those people objected to it's existence because it was Jewish. And not because they wanted "one united people, regardless of race, language or religion, to build a democratic society based on justice and equality". No, they wanted to wipe it from existence because they DIDN'T want those things. They wanted Islamic land ruled for Islam and only that. That was very clearly and openly stated and still is.
The inhabitants of modern Israel arrived back to it's sanctuary in majority due to extreme anti Jewish sentiment in it's surrounding countries. It is not a demonstration of a wish for an exclusive society. It is a demonstration of the necessity of one. My family, for example, in Iraq alone faced Jewish homes being burned down, business confiscated, being banned from doing their jobs, street lynchings of Jews, the Iraqi version of "Hitler Youth" parading the streets and throwing stones at them or spitting, nightly broadcasts of Nazi propaganda translated especially into Arabic and ultimately "zionism" being declared a crime punishable by several years imprisonment and basically every Jew being branded a Zionist. It was batshit crazy!
They didn't go to Israel, they went to Britain, but many did go to Israel because it was the only place there was where Jews would not be ruled over by people who hated them and actively discriminated against them. They were not allowed to live as "one united people, regardless of race, language or religion, to build a democratic society based on justice and equality". In fact, in countries where they had a presence for 2600 years, they were completely wiped from existence and stripped of all their property and nationality.
Then when they got their country, and freedom to live as Jews with Jewish beliefs and Jewish culture and the freedom to form their own government and a country in which they would not be treated as imposters or subordinates, they had the good grace to welcome a population that was 30% NOT Jewish, and unlike their compadres they gave those people equality under law and made them their neighbours. Jews have been ethnically cleansed out of every Arab country more or less.
All that said, none of it would have ever happened if people had allowed them to live as you are fortunate to live in Singapore, equal, and as valuable as those who had a "majority", but that wasn't the choice they were given. Or indeed if other people had not conquered their lands and decided to kill them, kick them out.
This is a classic reversal of reality really. Every country surrounding is a "Muslim" country. That is the only reason a Jewish country is needed. If every surrounding country were a Singapore style democracy where all citizens were equal and Jews were and always had been considered equal and completely valued members of society, then they would not need their own place.
Jews didn't invent the world, and they don't control what every other country does. They have a right to their home, and a right for them to be equals in it. And a right to defend it from people who hate them and wish to deny them their right to life, and to flourish with self determination.
