>>7361238This is also (and maybe even more so) true for Korea and it ties back to the fundamental difference in the cultural understanding of death and the beliefs surrounding that.
Eastern Asia has had several religious frameworks that, for centuries, have considered life as cyclical, death as a new beginning for another journey. The final form of something is not mere waste, it is the trace of something that has begun anew somewhere else, in something else. That's why poop is not necessarily seen as purely a negative thing, because what you reject is not an end, it is just part of a larger cycle life is constantly revolving in.
Meanwhile the European and overall Western traditions of early european paganism and then judeo-christian culture see life and death as much more linear : it is a beginning, and end and a stability during that life and the next. The remains of something are a proof of failure and finitude, something to be hidden and forgotten about since the essence is now gone from the world itself to a place that is an unreachable "elsewhere". So what you reject is shameful and necessarily unappealing since it, in a way, is a reminder that everything physical will at one point return to a primordial nothing while the fate of the soul lies in a place that cannot be percieved or understood.
