This has been a bad couple of years losing friends, relatives and personal heroes like Bowie, Prince and now Bourdain. I'm bothered by religious wishes and prayers throw around after a known atheist dies. A work friend passed quite suddenly as an example. and everyone said "oh he's in a better place" and "our prayers are with his family" knowing this man was proudly gay and a sarconic contrarian atheist. The family gave him a religious church funeral against his wishes. I know these words and actions are for the comfort of the living, and I had to bite my tongue and suppress anger at the seeming cluelessness and utter lack of respect. So the question is: What do you say? I like the alternative "Rest in Power", but even that implies an afterlife to "rest" in.
Rest in peace & Dust to dust both feel like they could go either way, atheist or religious.
