People shouldn’t be surprised by this.
The Christians who live in the Middle East are very anti-Israel. Zionism led to the seizing of much Christian land.
The largest communities in Lebanon and Syria hate Israel as much as the Muslims. Many of the most devastating terrorist attacks on Israel were organized by Palestinian Christians.
I despise terrorists, Christian or otherwise. I don’t believe one can be a terrorist and a Christian. The terms are mutually exclusive. I came to that at a young age growing up in an IRA supporting American Christian home. I’d have ratted out every one of them if I had the chance.
