There has never been a Palestinian state as such

This is using words to make a point that is entirely irrelevant to the issue. Palestine is and was the home of the Palestinians for centuries if not millenia. Just because didn't have an established "state" does not in any way invalidate their rightful claim to the homes and farms they lived in and tended for so long.

A Jewish minority might not be a problem if it weren't in the form of an aparthied state in which the Palestinians are forced into tiny bantustans with most of their water taken by Israel for it's own use, and the use of the settlers, and with high speed access roads (accessible only to the settlers) cutting up the territory and rendering it extremely difficult if not impossible for the Palestinians to have any mobility at all.

And with countless checkpoints where they are subjected to humiliation and even physical harm, and though which they are only allowed to pass at the whim of the guard at the checkpoint. Babies have died because as they were being born, the laboring mother was denied access to hospitals by virtue of being not allowed to pass through the checkpoints. Would you want to have to live like that? I can certainly understand why they wouldn't. I know I wouldn't like it at all.
