Brahmin is what a priest is called in Hinduism. I am one. It is very offensive for me to see Brahmin as a two headed cow-pack mule hybrid which people kill for meat and hide.. If you think this is a game, enjoys free speech etc., that is true, but then substitute the Redstag, the Brahmin, the Radroach etc with the priest of your religion and see if you feel the discomfort.
Bethesda has had trouble with this issue with previous version of fallout when Microsoft did not release the game in India. I made a detailed request through [email protected] and got the usual computerized response.
I believe it is never in a company's interest to alienate a group of users and never too late to correct a wrong. Come on Bethesda, leave existing religions out of your games and rename the 'Brahmin'.
