Well, maybe you're right. But I certainly wasn't aware of the real definition of who is an Israelite and who is a Jew (and I've read the Bible "through and through"), and I suspect most other people who think they understand the Old Testament don't understand it that well either. It is so easy to mix up Jew and Israelite, they seem to blend into the same thing, when of course we (now) know they are not.
I personally think Lost Tribe is doing a great public service by helping people better understand the basis of their faith. And if he choses to do that by pointing out those basic errors in threads, that's just fine by me.
Did you miss the part about bearing false witness?
