Didn't Arabs and Palestinians just flat out refuse to coexist with a Jewish state from the start?

"coexist with a Jewish state" is a bit of a contradictory statement. Arabs coexisted with Jews fine prior to the Zionist project. A Jewish state is by definition a state exclusive to Jews. That's the opposite of coexistnece by definition, and yes that is exactly why Arabs (Muslims and Christians alike) refused it.

Certainly if they chose to fight,

Resist*. they chose to resist occupation, expulsion from their homes, massacre and genocide.

fight, and lost, then they have to face the consequences which might include losing their land.

Ahh, so if someone fights you for your land, destroys your home and genocides your people, then they've earned it?? Well I should not be surprised that someone who lives in a nation founded on genocide thinks this is okay.

yes it's "wrong" to kick someone off their land, both parties have to at least be reasonable and willing to compromise

"hey man, I know I just took over your home and burned your family alive in front of your eyes. But you gotta be reasonable here and be willing to compromise!"

What more of a compromise do you need beyond coexistence? That's all Palestinians have asked for, and Israel continues to deny them basic rights, no matter how peaceful they are.

And I end with: Israel bad apartheid state. It is truly that simple.
