People have to earn respect in life to be respected in death. It shouldn't be automatic. We can feel sympathy for their family but as public figures, when the final curtain call happens, then we all have the right to question what impact they had on society, and to balance the gushing praise with a harsh dose of reality.
I didn't personally make any comments on the queens death for a few days, and I haven't made comments about Lawson, despite the fact I have extremely negative views of both. But this isn't North Korea, people should have the right to question the rose tinted views of these figures without being called out as being disrespectful in their death, because some of these people lacked respect for others while alive.
