I don't think the neglect of Palestinian Christians is at all naïvely neglected. It has to be deliberate since the bulk of the support of Israel is from Christian Zionists. Christian Zionists are the largest contingent of Zionists. Part of the reason that Judaism and Zionism is linked is to hide its racist nature.
Sorry, but by definition creating an ethnically pure society is racist. And Israel is undeniably an apartheid state.
