Moderates could and do live side by side without issues.
The “issues” are all those extremists. You can’t reason with them and they won’t stop until they destroy you.
All those extremists that were voted into power, are cheered for by Palestinians, and represent Palestine in the media and in international relations?
At first I thought you were talking about Israel and its extremist government, not Palestine, where about 44% of the people are under 18. For additional info, the last election in Palestine was in 2006 and Hamas got 44.45% of the vote while Fatah got 41.43%.
Even Palestinians outside of Palestine celebrate when there is a successful attack of their leaders (which is currently Hamas) on civilians.
Additionally, Fatah is a hateful and extremist group as well. This is a recent quote of Fatah’s president Mahmoud Abbas:
“They say that Hitler killed the Jews for being Jews, and that Europe hated the Jews because they were Jews. No. It was clearly explained that they fought them because of their social role and not their religion,” Mr Abbas says at one point. Later, he specifies that he was referring to the role of Jews involving “usury, money and so on”.
Fatah is often seen as a type of counter to Hamas, less extremist and secular. But Fatah sprung from the Muslim Brotherhood, just like Hamas. They are the group behind the assassination of the Jordan Prime Minister and the murder on the 11 Israeli athletes in 1972 Olympics in Munich.
