>They are only “mostly alike” if you carefully cherry-pick the ways in which you count similarity, while handwaving over the number and importance of the ways in which they are different. They are very alike if you look at all the other bodily activities and then rank them based on how different they are. Is 1mm a short distance or a huge distance? Without knowing the scale, you can't say if a 1mm difference is important or rounding error. 10000mm and 10001mm is not a big difference. .001mm and 1.001mm is a big difference. But both are only the difference of 1mm. In the same way, these bodily functions are different, but their differences are not great compared to the differences between these and other bodily functions. Urination is one of the only things I can think is closer... and it also has a lot of stigma around it.
