If someone has a better idea than Jacobs I would like to hear it. Otherwise I still suggest the OP check out his work and make up his mind for himself. At the very least it will get you thinking.
Seems like everyone is forgetting that we have no real answers. Only theories and guesses. Not sure why the posters on this forum try to shoot down everyone they don't agree with but it's pretty lame. Considering there are posters who push material from anti-Semitic sites and quote them as legit sources I would think there are immediate bigger fish to fry than trying to prove someone's ideas wrong when NO ONE has the answer.
