I guess waifuing didn't exist before Evangelion.
You didn't see males worshiping female characters like Sailor Moon, Bulma, Nausicaa.
The first time guys wanted anime characters as girlfriends was with Evangelion, which disgusted Hideaki Anno.
In my opinion it evolved a lot.
If you get any girl from Love Live like Maki or Nico. They are on another level of cuteness.
