Speciesism is not alone the institutionalized killing it’s also the ritualized killing.
It’s the sacrifice – done for the “human good”. The idea of sacrificing the life of the other for my own “greater good”, still holds the facet of the meaning the subjective-other must have had in my eyes, before or as I chose to sacrifice him/her. A sacrifice means to hurt/harm the other, to hurt/harm his/her integrity that is being put below some “other, ‘higher’ needs…”.
If I trace the killing back to pure “utilitary needs” humans had, how do you explain speciesism beyond its institutionalized face, where nonhumans have become pure objects of humans explaining them? That is, how do you explain ritual killings or speciesism in culture, arts, religion? Speciesist sadism/brutality?
The other is there.
