Notable philosophical views taken by Smith include criticism of animal rights, environmentalism, assisted suicide and utilitarianism.
Smith's 2010 book A Rat is a Pig is a Dog is a Boy is an anti-animal rights work which defends factory farming and human exceptionalism.
[9] Sociologist John Sorenson has negatively reviewed Smith's book A Rat is a Pig is a Dog is a Boy as a "misleading, bad-faith compendium of anti-animal rights propaganda, based on a single idea: human exceptionalism".
[6] Sorenson criticized Smith for ignoring the negative environmental effects of factory farming including habitat destruction and loss of biodiversity from deforestation.
[6] Philosopher Angus Taylor claimed that Smith has "little familiarity with the large range of literature on the moral status of animals".
