Can New Theory of Flight be Retrogressive?

Reviewer 2 of our article New Theory of Flight concludes the 6 page report by

• Regrettably, it is my conclusion that publication of any of this material, in any form, would be highly retrogressive.

Now according to the Free Dictionary retrogress means

• to return to an earlier, inferior, or less complex condition, 
• to go or move backward.

But if anything the New Theory of Flight does not go back to an earlier condition, which is signified by the fact that it is New. 

Further, the statement that publication of any of this material in any form would be highly retrogressive, would in order to be motivated seem to require that every single line of the article is old stuff. But this is not so.
