Obligatory story beginning in 1963, where computer scientist Les Earnest explains why he always entered "mongrel" when questioned about his race:
I once told a friend from west India to put “Aryan” down for race, but then stopped him and apologized after I realized that was mean-funny, not funny-funny.
I was really an asshole in my 20s.
This reminds me of "Seeing like a State" by James C Scott: attempts to simplify the world to allow generalizations about it always lose valuable detail.
