Wow, this is SUCH a horrible take, dude.
Tell you what, lots of people tooting that a celeb has died do, in fact, not "mourn" them. It's an info that a landmark of our lives has changed. Someone whose face we've seen and was *our age* has died. It's normal and good not to surpress the "oh shit" that comes with that.
Then there are some people who were fans, and they are hurting. Are you going to tell someone whose gran died "Thousands of grannies just died"?
