The vast majority of all the people who call themselves "Palestinians" weren't even alive whe people were being "kicked out of their homes" to create Israel in 1948.
The UK and US negotiated with those who claimed to have leadership authority over the land at that time. The Palestinians who claim they were kicked out of their homes were mostly nomads who by definition of the term, had no "homes".
Suddenly they want to nest because a bunch of Jews live in their old wandering grounds? I don't think so.
