I’m a Zionist because of people in my childhood including a Jewish grandmother.
My mother’s first husband was Jewish and my sister from that marriage visited her along with me as a child.
She peddled the Conservative Christian literature that supported Israel 50 or 60 years ago even some that was no so supportive of Israel.
The Christian radio preachers I listened to believed the land belonged to Jewish people.
Even Dr. Billy Graham said when I was a child that the Bible pictured Israel from the Mediterranean to the Euphrates.
The politics and so on I can’t change the socialism of David Ben Gurion, the nationalism of Menachem Begin but I’ve read the words of both men.
They did what they did great challenges before each of them great calamity as in the Holocaust and the conflict with their neighbors.
As for the Palestinian people Dr. Carl McIntire a famous radio preacher I hung out with listened to etc. saw a place for them in Petra southern Jordan if you will.
“White Christian Homeland” does not compute with me seems like Rob Reiner’s lexicon.
The reason you think “white Christian homeland” seems crazy and “Jewish homeland” seems reasonable is that nearly every piece of pop culture propaganda you have consumed in your life was created by people with a similar background to Rob Reiner.
