Nope, Israel is the most diverse country in the whole region without question

South Africa is diverse and was so during apartheid. This doesn't make it any less of an illegitimate apartheid state. In fact it makes it worse.

The zionist entity actively rejects that diversity by declaring itself an exclusively Jewish state. Palestinians can live there under various degrees of apartheid but they will never be considered equal to the Jewish population.

it is also also the only democracy in the region.

The zionist entity occupies the entirety of Palestine as well as parts of Syria. On that territory lives more than seven million Palestinians. Two million of those are considered citizens of the zionist entity and although they are systematically discriminated against and harassed they are allowed to vote.

In addition to the seven million Palestinians living in Palestine, more than three million Palestinian refugees lives outside of Palestine and are being denied their right to return to their homeland by the zionist entity.

Of the zionist entity's population seven million are Jews.

Why all of these demographics? Well, of a population of seventeen million, Jews make up a minority. However while all seven million Jews are allowed to vote in the zionist entity's elections, only two million Palestinians are allowed to.

As a result result of having elections only for the elite ethnic minority, politics of the zionist entity has moved to be dominated by far right Jewish supremacists.

How democratic is that? How democratic is a state that explicitly and unapologetically declared itself to be a state for a minority of the population?

Palestinians enjoys very limited political freedoms and are severely hindered in their abilities to express themselves. They can get convicted by zionist courts for the crime of posting on social media that somebody has been murdered by the occupation forces. Even passively consuming "terrorist" media can land you in jail.

Calling the zionist entity democratic is to make a mockery of the concept of democracy. But even if you believe it to be democratic, how does that justify settler-colonialism and apartheid?

On top of that, Israel is also the only country in the region that has womens and LGBTQ+ rights written into it's law

The zionist entity is pretty unique in the world by still having miscegenation laws. A Jew and a Muslim cannot legally get married in the zionist entity. All family law is governed by theocratic and unelected conservative religious institutions, creating separate legal systems for each religious demographic, no matter whether the individuals getting married shares these strict religious beliefs or not. As a consequence, there is no such thing as civil marriage in the zionist entity either and certainly not anything like gay marriage.

All I did was criticizing the antisemitic generalization of all citizens of Israel as casual child murderers

The zionist entity is a casual child murdering entity. Zionism is an ideology enabling casual child murdering. The evidence for their evil is overwhelming. But for the people of the zionist entity you can't really generalise any more than you can with any other population of millions of people. Each of them have the same potential to be good morally upright human beings as anyone else. With that being said, election results and polls suggests that a large portion of that population of the zionist entity subscribes to deeply racist Jewish supremacist ideas. This doesn't mean that they all share these views or that those who do cannot be deradicalised or that these beliefs are essential to Judaism rather than being offshoots of western imperialism.

Opposing apartheid systems is not racist. Opposing apartheid ideologies is not racist, even if those beliefs are prevalent among a certain ethnic group.
