Just like a person who is conversant with medical science. He is called medical man or a doctor. It doesn't matter whether he is born in India or born in America or whether he is black or white. It doesn't matter. One must have the qualification of a medical man, and he is called a doctor. Similarly, Bhagavad-gita also accepts the brahminical culture, the brahminical culture. Brahminical culture means the social position in which everyone is assisted to elevate himself to the highest position of understanding the position and the constitution of the soul. That should be the aim of human society.
