When I had dinner with [Anno], he revealed to me that he “originally wanted to shoot a ‘school drama’ post-armageddon (World War III.)” Toward the end of the TV series Evangelion, there is a “dream sequence” using the framework of the school drama. Anno stated that “that part was supposed to be the body of the story.” In fact, since Anno was in the state of depression just before the production, the part on the armageddon expanded and the whole story became an “Oedipal drama with the armageddon in the background.” But in its initial conception, the armageddon (World War III) was required to set up a “school as a paradise,” much like the stage for the dating simulation game Tokimeki Memorial. That is what Anno said.
While I don't doubt that Azuma is right about there being some work which served as an inspiration for the "parallel world" sequence, it seems that, according to Miyadai's account, the concept of that world was part of Eva's original intention. In that case, the "parallel world" sequence was not originally conceived of as a parody.

And they didn't, I remember Number-kun translated some Anno interview a while ago where he was discussing one Eva doujinshi with its author (saying he could never depict Asuka's issues as a girl with mestruation as well as she did IIRC)
That author was Nobi Nobita aka Nariko Enomoto, and actually there is an article written by Patrick Galbraith where he claims that Anno actually used elements from one of her works in the "theatrical versions of the series" (I was about to write EoE, since her interview with Anno took place just before that, but I wonder if he means Rebuild?). Anyway, it's surely far from impossible that Anno would do something along the lines Azuma indicated.
Edit: Want to think more about other comments.
