Let us not get into the cruelty to animals in India and USA. We claim to be against killing of cows, but our cows roam the street and not fed, and generally neglected. The horses and bullocks used as beast of burden are beaten mercilessly. Stray dogs are infested with all deceases and no body cares. Our elephants are chained for life. Our zoos are antiquated, and animals are in cages.
When it comes to animal welfare we have a lot to learn.
I agree that they raise farm animals for food in the west, but they have compassion to take care of them as well.
As far as milk is concerned, there are ethical diary farms. You can also switch to soy Milk. We can only claim to do least harm, but we do harm living things, like plant, bacteria, and animals in the way we live our life. So let us not judge others.
