I’m curious for your reasoning behind this. Is this lack of knowledge outside of the movies/disney meta? Lack of knowledge about the writing behind it? Do you know shit about Star Wars instead? I’m actually curious what you mean because so many fans know so many different fragments of an almost unattainably large lore space that you sound incredibly wrong and right at the same time.
Missing an extremity is an actual medical condition… I get your point about other kinds of conditions that are congenital or otherwise not directly due to physical harm. PTSD would be a good example of what could have been included in that case as well (this might actually exist in some form from disney). With how poorly so much of it was handled, it’s probably for the best that they didn’t try to tackle autism or Downs syndrome at the same time though.
