Respectfully,
So because some 'demanded' it more it should happen?
As for the last paragraph, you can discuss the UN. Mainly the emergence/force of Zionism, the Balfour declaration but importantly the sympathy towards Jews after the horrors of the holocaust.
Palestinians were not uniformly rejected by neighbouring Arab countries.
over 300k went to Jordan (recently the gov suggested nearly half of Jordanians have Palestinian roots)
Approx 100k went to Syria and Lebabon/Egypt also took on many Palestinians.
I know people who have visited the camps in Jordan where Palestinians are still living.
This is false info that only serves to continue to describe Arabs/Palestinians as less than human and no-one wants them.
I'm living in my house, I've been here for generations.
Some guy comes along and tells me to move at gunpoint but offers my Israeli citizenship. Maybe practically I should take it, maybe my pride might tell him where to go.
On the other hand, I've got nothing and someone offers me 55%, sure I'll take it.
