it’s called English Israelism — the idea that the Aryanic English are actually descendents of the lost tribes of Israel. I know — it’s ludicrous and historically and genetically wrong, but there were many who believed it and many who do, you see this in some Baptist groups too.
I have a Jewish friend who I was explaining to that when David Koresh read the Bible and it said “Jew” he read “Honkey” and where it said “Zion” he read “Waco Texas”. He laughed his head off! He had never heard such a ludicrous thing!
