Yeah, I don't want to smear the work of good people. Neil deGrasse Tyson gets/got a surprising amount of hate mail from children due to his involvement in the definition of 'planet' and the reclassification, and man, he seems like a kind and thoughtful person. Obviously, there are people who wish to see Pluto be classified a planet that don't want good people to get hate mail from children, but this isn't the type of thing that should be "sad" or even controversial.
