I admit, it's second-hand for me, but I have a couple of cousins who are really close to me and who are diagnosed and expressed the same things I did.
I appreciate that it's not your experience, but when I watched this movie, I saw them being made fun of, and they did to.
Can you appreciate that standpoint?
Maybe it's cultural, I don't know.
I think your POV is as valid as anyone else's. Different people will get different things out of a work of art. (Heck, if we all saw LnC from the same POV, we wouldn't have a board full of discussions and fanfics from different viewpoints.)
