Death is a terrible thing, respect for anyone who dies and empathy for the people who mourn them is like an unwritten rule, part of being human. It's only the most insignificant proportion of people that die who it can be said attract negativity because of bad things they did in life. It is human nature that some peoples deaths attract celebration due to their infamy.
Yes there should be respect for everyone and anyone who dies but we cannot mourn for or pay respects to everyone even though it is sad good people die every day. People mourn the famous because they are recognisable to them, they know facts about their lives, admire what they did that kind of thing. Even though there is the detachment of not actually having them as a friend they still feel they lost a little something or just feel sad that it happened.
When I see a publicly known figure has died and there is a thread about them I either post my respects or if I had no affinity for them just pass by. Leave the people to pay a little tribute to someone who has died and done no harm to others.
Peaches Geldoff, it's sad she died, terrible for her family, I had no affinity for her only knew who she was because of her famous parents, she was a young mum who had a lot of sadness in her life.
