I'd just like to interject for a moment. What you’re referring to as Waifu, is in fact, Anime girls/Waifu, or as I’ve recently taken to calling it, Aniem girls plus Waifu. Anime girls are not a waifu unto itself, but rather another free component of a fully functioning Waifu system made useful by the love of an anon, dedication and vital loyalty comprising a full Waifu as defined by /a/.
Many /a/ users post an invalid version of the waifu system every day, without realizing it. Through a peculiar turn of events, the version of Anime girls which is widely used today is often called “waifu”, and many of its users are not aware that it is basically the anime girl system, developed by japan. There really are waifus, and people are using it, but it is just a part of the system they use.
Anime girls are the kernel: the program in the system that allocates the anons love resources to the anime girs that you love. The anime girl is an essential part of an operating system, but useless by itself; it can only function in the context of a complete love system. Waifu is normally used in combination with the anime girl operating system: the whole system is basically anime girls with waifu added, or Anime girls/Waifu. All the so-called “Waifus” distributions are really distributions of Anime girls/Waifu.
