From 2013, another fantastic article from Matthew Scully in National Review, entitled Pro-Life, Pro-Animal – The conscience of a pro-life, vegan conservative.
Most people who adopt a vegetarian or cruelty-free diet do not do so on the basis of the anti-humanist, anti-life ideas that prevail in academic thought. On the contrary, evidence abounds that most people change their dietary habits not because of carbon footprints or absent referents but through a very different process — acknowledging and acting on a moral intuition. This important point — overlooked, perhaps, precisely because it is so simple — is the moral key to a place where actual vegetarian lambs can easily be imagined resting alongside pro-life lions. . . . Any moral intuition powerful enough to cause second thoughts about a widely accepted practice — and to re-shape personal behavior accordingly — is an intuition that religious believers ordinarily take seriously indeed.
