First, I don't give much attention to the conspiracy theory you are putting forth to explain edits - I'd rather attribute them on common sense and objectivity. Second, Lewis is polemical, to say the least. I don't believe he achieves the unshakeable credibility you attribute him, and he has proven able to be (very) wrong, due to his political choices (because he has a political career as well). Finally, Lewis' contribution to the Rhineland/Khazarian Hypothesises is dated, minimal and POV. What about my suggestion that you write the deleted section's counterpart?
