A Jain doesn’t have to purchase milk from a factory farmer.
And AFAIK even the most stringent vegans don’t brush insects from their path with every step, or avoid onions and carrots because it causes death.
All of these result in suffering much worse than egg harvesting imo. Reluctant dairy eater btw
But, that said, a mark of being more important than a lesser being would kind of be the virtue of still empathizing with that being, even if we assume there’s a hierarchy.
And considering you and I are really just elaborate transport vessels for E. Coli and a lot of fungal spores, I’m not sure we should assume there’s a hierarchy.
