was invented by people who were jealous that other people liked the same Japan-related things they did and so they desperately started calling the others "weeaboos," in an effort to make them feel bad about what they like and possibly make them quit and move on.

Actually, the term "weeaboo" came from the Perry Bible Fellowship in an unrelated context. It eventually was adopted as the replacement term for "wapanese".
So, um, you fail or something.
