No. Please stop using the blatantly misguided comparison between Israel/Palestine and David and Goliath.
Goliath, to start with, was recorded to be a legitimately powerful warrior who openly used his strength and monstrous physique to win battles/wars. His strength, fighting prowess, and superhuman body was acknowledged by both allies and enemies.
Israel is far from being legitimately powerful in any way. The illusion of power comes from the open line of support it has with the US/ US military...itself a paper tiger who only fights weak or weakened foes, and struggles to pull out wins even then. (Korea, Vietnam, Iraq, Afghanistan).
Secondly, Goliath challenged his foes openly and directly, and fought them in a straightforward manner like a true warrior. Israel has historically always avoided direct battles rather choosing to play dirty games like assassinations, threatening civilians, bribing their foes, and manipulating political actors into serving their (short term) interests.
Palestine is both Goliath and David. Its has in its struggle both people of immense individual strength and might, and those who rely on their courage and mental prowess. Israel has no historical analogues because history rarely record cowards and petty criminals as anything other than nameless pests they are.
Even the Arabs despised Islam before embracing it. Islam means submitting to the true laws of God. It's natural I suppose for people who are lost in their own narcissism to be fearful, or angry even, to be told to get over themselves and embrace reality.
One thing that shouldn't be ignored is how people maintain the ties to their new faith after the initial embrace. Regardless if they are Arabs, Kurds, Turks, Iranians, Indonesian, Indians, Nigerians, Bosnian, Japanese or American, Muslims generally take great pride in their religion.
The same cannot be said of Christians, where many are reluctant to embrace it as core aspect of their identity. I suppose the same can be said of the Jews as well. They view their faith often as a baggage tied to them by greater society, hence the high number of atheists and non-deists among Judeo-Christian populations.
Why wouldn't she support Palestine? Why would any smart, educated and capable woman willingly go and support a regime, an ideology, based on the patriarchal establishment such as Israel, moreso after all the shit Hillary went through in America because of the same patriarchal mindset of the Republicans?
On the other hand we have Palestine, where women are respected for who they are and what they are capable of, regardless of faith. You don't see strong, fiercely feminist women mirroring Hillary coming out of the Zionist camp. Not one.
In Palestine, feminism is baked into the very fabric of the culture, nurturing strong women who embodies all the qualities Hillary is famous for. Full of compassion, love, fierceness, intelligence, pride and sense of justice. In Palestine, it is the womenfolk who are sustaining the struggle for their liberation, through their immense strength and sacrifice. To accuse Hillary of forsaking these women to appease the vile Zionists who are full of toxic masculinity and patriarchal attitudes, shows extremely lack of character assessment skills.
Anyways, its all pointless now. Trump has won the election and we just have to fight this battle on top of the thousands of others, in the ultimate war for justice and liberty.
