"But since is lost on Mr. Rajshekar. He has published a book in the West, titled Dalit — the Black Untouchables of India. On the cover is a photograph of, I presume, the writer. And the first thing you notice is : but this man is not black. He is quite a Caucasian, or white man, though slightly more suntanned than Europeans, but not at all a negroid type. And you start to realize : this man is a crackpot. In order to attract American Black support, or for other propaganda reasons, he makes the caste system into a racial issue. The rich white Aryan Brahmin invaders oppress the poor black non-Aryan Shudra natives. Now this has a lot to do with Hitler. He too was a crank racist."
