I think it’s a classic conflation of a Nation and a State. I believe all Nations have a right to exist - that a people with a common cultural identity have a right to that identity and to express that identity through their other rights, such as Speech and Assembly.

There has been a Jewish Nation for hundreds of years, before there was a Jewish State.

I don’t think it’s controversial that Jews (or even those who consider themselves Israelis in particular) have the right to form a government, that can democratically pass laws to apply to those who willingly submit to that nation.

The controversial part is that Government’s formation of a State that expresses sovereignty over territory it has no right to; territory that has been held for hundreds of years by people who are not members of the Jewish Nation, and who the Israelis have no desire to include nor enfranchise.
