::::Melton does not say Hubbard didn't say it, just that it cannot be substantiated that he did say it. On page 55 Melton says,  Footnote 2 on page 74 then says,  My impression is that there are ample sources for Hubbard having discussed the matter, though none attributes this specific quote to him. What's in the article now is a bit suboptimal, as it says much the same thing twice and does not mention Orwell, just "someone else". In my opinion we should say that the statement is often attributed to Hubbard, that SF colleagues recall him discussing the matter, and that it apparently was Orwell who first said it.
