yet refuse to negotiate for a viable piece?
Look at any colonized people who have made peace on their colonizer's terms for why they might not want to do that.
Let's see here, just off the top of my head:
Native Americans, Native Australians, Native South Africans.
To be fair, Palestine already resembles the reservations and slums the native people I mentioned have been forced into by their colonizers.
I can say, with absolute certainty, that is not the norm.
For every sale they make, there are countless others they don't. And they still have to put in the time.
I've gone through many realtors looking for a house, all of them gave me hours of their time and didn't see a penny in return.
That said, I don't think realtors are necessary and we should push the idea that people shouldn't use them unless they think they need to.
