I have seen vegetarians not having eggs/egg products but no problems with milk and milk products. I know from reliable sources that the eggs supplied in U.S markets are unfertilized and hence cannot turn into a live form upon incubation. The dairy farmers
kill majority of the male chickens for meat purposes keeping only the female chickens for unfertilized egg production. (the rationale being that it saves on space and resources) for the farmer-- although igniting sentiments of male chauvenists!! This makes eggs no
different than other acceptable edible animal protein for vegetarians such as milk/dahi/yogurt. Not eating egg/egg products for religious reasons but consuming milk at the same time doesn't make sense in this scenario.

On the other hand, cheese (not paneer) in US and european countries is mostly made using an enzyme (rennet) gotten from calf stomach lining after killing it for meat purposes. Though the enzyme is used in miniscule amounts during cheese making, it should still
make cheese a non vegetarian food, unless the
label says: microbial rennet instead of calf
rennet. So are vegetarians really vegetarians?
