Note
Suffering and treatment are not the problem
When you make it about suffering, harm, or how animals are treated, they think that is the problem to solve, humane farming, backyard eggs, better conditions. The problem is using someone for your purposes at all. See also: the symptom language trap.
Gives ammo
Veganism is about reducing suffering. Look how this cow is suffering.
Gives nothing
The issue is exploitation, using them for your purposes. Do you agree that is wrong?
