One of the best-known examples of racism is the “Guess Who’s Coming To Dinner” scenario where parents are scandalized about their child marrying someone of a different race. Pew has done some good work on this and found that only 23% of conservatives and 1% (!) of liberals admit they would be upset in this situation. But Pew also asked how parents would feel about their child marrying someone of a different political party . Now 30% of conservatives and 23% of liberals would get upset. Average them out, and you go from 12% upsetness rate for race to 27% upsetness rate for party – more than double. Yeah, people do lie to pollsters, but a picture is starting to come together here.
The Maitrayaniya Upanishad , also known as the Maitri Upanishad, is found in the black Yajurveda. It consists of seven Prapathakas (lessons). The first Prapathaka is introductory, the next three are structured in a question-answer style and discuss metaphysical questions relating to Atman (Self, Soul), while the fifth to seventh Prapathaka are supplements.  However, several manuscripts discovered in different parts of India contain lesser number of Prapathakas , with a Telugu language version showing just four.
