Before Israel was founded the Christians among the Palestinian Arabs numbered 15%..even a bit more if IIRC. George Habash and other Christians were big in the PLO and other liberation fronts.
With the 1948 war and founding of Israel the Christian Palestinians had the same anger and grievances the Muslim ones did. So of course they were anti-Israel and anti-Semitic like the Muslims
This percentage is down to what? 5% or less these days due to explosive Muslim birthrates and Christian Palestinians immigrating to Europe and America. Same as what happened in Lebanon which was heavily Christian until 30 years ago.
Islamic crap and cruelty has rubbed off on other Christians too. Such as Spain where it is speculated that the cruelty of the Conquistadors was something they got from the Muslim occupiers of Spain.
You’re correct, of course.
There has been a sea-change, recently among Christian Arab Israelis, largely I think because of persecution by Muslim Arabs and acceptance by Jewish people.
For example, they demanded the obligation to be drafted to the IDF, like the Druze.
And they’ve done well in other ways. For example, Christian Arabs are the most educated and wealthiest Israelis as a group.
