@BillRM,
Simply because the Palestinians feels helpless against the Israelis, and they continue to suffer loss of land, loss of jobs, and their freedoms.
You just don't understand human nature; if you were put in the same position as the Palestinians, how would you react?
When people feel helpless, they will resort to what they think is their only chance for survival.
It's the Israelis who are stealing their lands, limiting their opportunities for business/jobs, and controlling the free movement within their own country.
Do you know of any Jew who would tolerate such control over your life?
