: That paragraph is a good find. Sources which contrast various aspects of caste[-like] groups are very useful for developing this overview article. Such sources should help move it away from the current structure which is mostly an amorphous enumeration of what one author or another called a caste for some definition thereof, definition not necessarily spelled out. (The current structure of this article is a bit reminiscent of the article we have on fashion faux pas and of the "Allegations of apartheid" arbitration where "they do it too" articles kept popping up based on mere mentions in the press.)
