“Why is it legal to kill animals but illegal to abuse them sexually?” — answering the question.
Industrial slaughter for overconsumption and zoophilia are both forms of cruelty that exploit vulnerable creatures incapable of giving consent.
The state legalizes mass killings at slaughterhouses, justifying the annual destruction of tons of unsold meat to protect billions in corporate profits and tax revenues. Zoophilia, as a manifestation of personal sexual deviation, brings no financial utility to the economy, so it is hypocritically criminalized, using “humanism” and “public morality” as a classic legal facade.
In capitalist logic, the real measure of legality is not compassion for a living being, but its commercial value. Consequently, violence against animals is rendered illegal when it generates no market revenue.
