Over the centuries humans have folded themselves into power structures that benefit the few at the expense of the many. In the same way that the imperialist subjugates and exploits the third world and the capitalist exploits the worker, the human has positioned itself at the top of an explotative and murderous relationship to nonhuman animals. The beneficiaries of the status quo will emphasise their personal benefits, while refusing to acknowledge even so much as the existence, let alone the moral value, of their victims. When forced to engage with them, the justifications are often times the same - considering the outgroup to be deserving of oppression due to a perceived lack of valuable traits, be it intelligence, the ability to "contribute" to society or emotional "depth". If we let our morality only apply to our chosen ingroup rather than extending it to all sentient life, we will inadvertantly leave intact the same unjust power structures we readily criticise in the rest of society. Working towards a life that doesn't contribute to animal exploitation is not just possible but necessary. Go vegan.
