I mean… There’s a saying that goes “shining a turd” for a reason. Even healthy poop is still poop. That’s why people aren’t usually clamoring to become a gastroenterologist when they grow up. It’s likely a big factor as to why the gut microbiome wasn’t really researched well / discovered until later compared to discoveries in other medical fields.
Trust me, they don’t find poop repugnant because it’s unhealthy, it’s because it’s poop. Even the healthy ones are waste products of the body.
