I've started by steelmanning the strongest anti-vegan arguments. I'll finish writing the responses in a few months.
If you want to truly defend a position, you need to understand the best arguments against it. Here are the strongest, most compelling arguments against veganism that I've encountered—presented as charitably as possible before I respond to them.
Introduction: The Gap Between Belief and Action
Most people aren't vegan, but it's rarely because they've sat down and carefully constructed a philosophical argument against it. Usually, it comes down to practical barriers:
- Lack of awareness about the ethical implications
- Convenience and accessibility
- Taste preferences
- Deep-seated traditions
- Habit
Beyond these practical barriers, we often encounter justifications that serve to protect us from the discomfort of cognitive dissonance. We might say, "I love my dog, but I eat cows because cows aren't pets." While this resolves the immediate tension, it doesn't hold up to rigorous ethical scrutiny.
However, there are serious, thoughtful arguments against veganism that deserve to be taken seriously. To truly test the strength of the vegan position, we shouldn't just attack the weakest excuses. We should face the strongest counter-arguments head-on.
In this article, I will steel-man each of these arguments—presenting them in their strongest, most charitable form—before offering my response. If veganism is the ethical baseline I believe it to be, it should be able to withstand the toughest scrutiny.
The Strongest Arguments We'll Examine
- 1. Vegan Diets Are Nutritionally Deficient
Humans need animal products to thrive—without meat and dairy, you'll be weak, deficient in B12 and protein, and unable to perform at peak levels.
- 2. The Natural Death Argument
Hunting provides a quicker, less painful death than what animals would experience in nature—so isn't it more ethical?
- 3. The "One Whale" Calculation
If killing one large animal feeds more people than crops that kill thousands of small animals, isn't eating whales or cows more ethical?
- 4. Crop Deaths and Field Animals
Plant agriculture kills thousands of field animals through harvesting and pesticides—more than eating a few cows would. • Response needed
- 5. Plant Sentience
Plants respond to damage and communicate with each other—if we can't prove they don't suffer, why is eating them ethical? • Response needed
- 6. Accessibility and Privilege
Veganism is a luxury belief for wealthy people—it's inaccessible and even colonialist to expect everyone to adopt it. • Response needed
- 7. Animals Don't Suffer Enough to Matter
Animal suffering is qualitatively different from human suffering and too minor to warrant significant moral concern. • Response needed
- 8. Humans Evolved to Eat Meat
Our biology—teeth, digestion, and evolutionary history—proves we're designed to eat meat, making it natural and ethical. • Response needed
- 9. We Have Bigger Problems to Solve
With genocides, wars, and poverty, we should prioritize human suffering over animal welfare—moral triage demands it.
- 10. God Gave Us Animals to Eat
The Bible explicitly permits eating animals—God gave us dominion over them and Jesus himself ate fish.
- 11. Animals Are Here For Us
Farm animals were bred for us—it's their purpose. They wouldn't exist without us, and their evolutionary success proves this relationship works.
- 12. Veganism is Just a Religion
Veganism operates like a faith-based belief system with unprovable axioms and evangelical behavior—it's secular religion, not rational ethics.
- 13. Perfect is Impossible, So Why Try?
You can't live without causing harm anyway—breathing takes oxygen, existence creates waste. Since perfection is impossible, why obsess over eating animals?
