Humanity's systematic killing of other animals, as well as the subjugation of groups of humans, did not begin until males created weapons and began h… - David Nibert

The profound cultural devaluation of other animals that permits the violence that underlies the animal industrial complex is produced by far-reaching speciesist socialization. For instance, the system of primary and secondary education under the capitalist system largely indoctrinates young people into the dominant societal beliefs and values, including a great deal of procapitalist and speciesist ideology. The devalued status of other animals is deeply ingrained; animals appear in schools merely as caged “pets,” as dissection and vivisection subjects, and as lunch. On television and in movies, the unworthiness of other animals is evidenced by their virtual invisibility; when they do appear, they generally are marginalized, vilified, or objectified. Not surprisingly, these and numerous other sources of speciesism are so ideologically profound that those who raise compelling moral objections to animal oppression largely are dismissed, if not ridiculed.

Today, based on the growing body of work by ethologists and biologists about the profound mindedness and emotional life of other animals, we can assume that, for the most part, the other animals' experience of capture, enslavement, use, and slaying was one of suffering and violence. While much of their treatment unquestionably was in the form of direct physical violence, the animals' systematic enslavement and oppression also resulted in their inability to meet their basic needs, the loss of self-determination, and the loss of opportunity to live in a natural way—an indirect form of violence known as "structural violence." Archeological findings of the remains of early enslaved other animals provide evidence of their suffering. Generally, examination of the remains of animals held captive thousands of years ago reveals bone pathologies resulting from physical trauma, poor diet, chronic arthritis, gum disease and high levels of stress.

The "" of highly social animals—which developed out of hunting them—was no partnership at all, rather, a significant extension of systemic violence and exploitation. The emergence and continued practice of capturing, controlling and genetically manipulating other animals violates the sanctity of life of the sentient beings involved, and their minds and bodies are desecrated to facilitate their exploitation: it can be said that they have been domesecrated. Domesecration is the systemic practice of violence in which social animals are enslaved and biologically manipulated, resulting in their objectification, subordination, and oppression. Through domesecration, many species of animals that lived on the earth for millions of years, including several species of large, sociable Eurasian mammals, came to be regarded as mere objects, their very existence recognized only in relation to their exploitation as "food animals" or similar socially constructed positions reflecting various forms of exploitation.
