While Palestinian Christians are Christians, they have grown up with the Palestinian identity...While most probably refrain from violence, many support the anililation of Israel...And as most of these 'Christians' are mostly Orthodox and then Catholic, they do not believe Israel has any biblical claim to Palestine...
While there are not many/any real headlines depicting Palestinian Christians attacking Israel, the stories are contained within other articles...
Here's a mention of rock throwing Christians in one article
And here's an interesting part of a book(?) on the youth Palestinian identity and an interesting take from a Palestinian rock throwing Christian...You will have to read a little or scroll down...
There's plenty of info out there...
How many American chrstians are aware that Israeli chrstians traditionally support and vote for the Israeli Communist Party???
What you say is true of most Christian Palestinians, it is not true of Lebanese Catholics, most of whom are very pro-Western in their political orientation (many of them even looked upon Israel as an ally during the civil war in Lebanon). The Christian Lebanese diaspora is also among the most economically successful immigrant communities in virtually every country that they have settled. In ever way, they are a far cry from their Muslim counterparts.
