or they live under a secular, democratic Palestinian state from the river to the sea where both the Jewish and Arab population live as equals.

I don't see the people who voted in and fully supported:

the Zionist settler-colonialist project and it's ambitions, the full extermination of the Palestinian population.

Participating in a secular democratic Palestinian state in good faith. I also don't see the religious and nationalist zealots that make up the current government and its core supporters agreeing to leave.

but they are all in a United Front against the Zionist regime.

United fronts don't tend to outlive the enemy they are united against.

I also don't understand what the your alternative is? Palestine is unstable as fuck under two states. so what are you proposing?

I don't see how a single state including all of these groups, under a secular democratic government can come into existence.

The sort of societal change necessary would require tactics similar to revolutionary China or Russia, full wealth redistribution, some form of widespread re-education and some form of vanguardist government to oversee the transition. The majority of people in Palestine would not support those measures, and neither would the surrounding powers.

I really hate people who speculate and criticize without offering any actual implementable plans.

My lack of ability to think of a solution to the problem does not stop me from seeing the issues with the ones that are proposed. (Or rather skipped past in most cases.) We all, I would hope, want to see an equal, democratic and secular Palestine from the river to the sea, but how does that happen?
