Really feel like I'm looking at somebody with 1 foot in the grave.   Exactly.  There's a reason people have a gut revulsion to someone who looks like that, and it's not "society."  Nobody claims "societal beauty standards" are why people find Uncanny Valley robots creepy--not even the most evolution-denialist SJWs.  How could it possibly be any different for members of our species who no longer look fully human?
