My girlfriend is a Hindu Brahmin and I'm a Hindu Kshatriya. We are both pretty Americanized but she was raised in a much more religiously conservative environment than I was. It bothers her when I eat beef and while her happiness really means a lot to me, I don't want to do something only to make her happy and ignore my own desires. However, my religion (Hinduism) is actually important to me and I don't want to do something that would go against it.
Given these considerations, should I stop eating beef?
