Well, you gotta remember that in the Bible, the Jews (then Hebrews before becoming Israelites) are God’s chosen people and God aids them in destroying other nationalities all the time in the Old Testament. Hence the 12 Tribes and Israel coming about.
Christians will back the 12 Tribes of Israel because they’re the foundation of their religion. You can’t have Christianity without accepting God chose the Jews as his people and created the Kingdom of God and distributed it amongst Jacob’s 12 sons. If this is not true, nothing after it is either including Jesus as the Son of God, gentiles being accepted, and being judged be the 12 thrones in End Times.
So I think you will find most Christians support it while those that don’t simply don’t know their own religion too well.
So, yup! Pretty fuckin’ scary. But it’s not like it’s anything new. Lots of people have been killed in the name of religion before us and lots of people will once we’re gone.
