Your argument assumes morality has objective weight -- that suffering is actually wrong, not just unpleasant to you. But in a godless, material universe, "right" and "wrong" reduce to personal preference or social consensus.
If there is no transcendent moral source grounding those values, then saying veganism is morally correct has no more ultimate meaning than saying you prefer it. Without objective morality, all worldviews (including yours) collapse into nihilism.
