It’s worth noting that Caitlin Doughty is a certified mortician, and the person she’s interviewing, Katrina Spade, is the driving force behind that particular human composting facility. They both, together with a slew of other people, have campaigned to make human composting legal in New York and California.
So it’s not some weird troll BS, these are professionals discussing their work, which at least for Katrina is human composting, and Caitlin, dead bodies in general.
