hi,
If you give explanation (for milk being non vegetarian) that since it is originated from animal, then it is completelty wrong. Anything that is considered non-veg is living tissue in one stage or other during cource of its life. Milk was never a living tissue.
On other hand if you say milk is vegetarian because cow feed in grass then also it is a wrong explanation. Goat also feed on grass, its meat is non vegetarian though tissue and cells of meat are also synthesized by a same bio-chemical mechanism (from which milk is produced.)
I would consider milk as vegetarian food because it do not involve any living part or any other part that was living once.
