I liked this article from The Atlantic, Enter the Grief Police.

Bowie's death is the first recent celebrity death that actually affected me and I saw a few people online saying essentially to get over it, that's something I've definitely thought about other outpourings of public grief.

So it was a bit of a kick in the face for random people to make assumptions about what I'm feeling and a reminder to not be so flippant with other peoples emotions. Mostly I just ignore the jerks though.
