Like the graininess that makes up a picture in full, the voices make up sounds behind sounds in whispers, building up each to each.
What's the point in ever getting one's knickers in a twist over the word fuck? How does it make sense in any conceivable way? It doesn't demean anyone, it doesn't damage anyone, it doesn't slur or discriminate against anyone, it's just a couple of phonemes that literally mean 'this is an expletive' and have no other content. It's the platonic ideal of a swear word.
