If you really mean it and you can relate to it - fine, but nothing worse than those half-assed meaningless RIP's in the comment sections on Facebook, Instagram and so on.
How many of the people posting those comments are sincere, and how many couldn't give a fuck and just post them because they think they are supposed to do so, cause demency demands it?
You don't really feel/mean it? - don't post/say it. Feigned/insincere mourning is worse than saying nothing at all.
It's a slap into the face for those who are genuinely in pain of losing someone close. If you happen to have lost someone close in your life, you know those kind of people are the least you want to come across in times of pain.
Only person I saw making multiple mourn posts was Osman, and someone else said they cried. Hardly anything to get over-analytic about. GordoCentral's posts were stranger.
It was a sudden, unexpected, shocking news and of course sad (always is when you hear about these things) even if not debilitating (doesn't have to be for it to be sad, odd stance/argument), and most left comments stating as much. I don't believe there's anything after death, so I don't say RIP, but those who do wished that. Don't see what's wrong with any of that.
Yeah, there are annoying fake Charmins out there, but you guys are the ones exaggerating here.
