I'm looking back on any discrimination against South Asians...I don't know. Well for one thing, one interesting loophole in discrimination, is that there is white guilt about discrimination, as a group they know it to be wrong and they don't like carrying it out in abstract. When there is a stereotype-breaker, they go for it completely. So Asia lies north of the equator, meaning South Asians lie closest to the equator, more light but also more heat meaning less clothing more exposure to light, so what do you get? Darker skin, particularly in Sri Lanka. Born under an equatorial sun, as Harriet Beecher Stowe put it in Uncle Tom's Cabin. So the deal is they are dermatologically dark, like Fitsch type 5 (a scale from 1 to 6 measuring skin darkness and tanning in response to sunlight, not truly synonymous but close enough to be useful), but they're Indoeuropean, always known to be the same language group as eg the English and Norse. Known kinship, and the intent was to accept them, and they invented 0 come on, super smart great at chess invented that too.
So by now the desire in principle to accept them in combination with them working like crazy--the most basic way to hack discrimination--and in addition, outpacing other minorities in certain fields--like there was a blogger on Wall Street who talked about being East Asian on Wall Street, and compared it to being South Asian saying it was rough because there were I think no managing directors (MD's as they're called) on Wall Street that were breakaway successes. Whereas there were South Asians there were. (I think Indians, the article said BSD Big Swinging Desi, meaning Indian, vulgar yes Wall Street can be vulgar, dude it's all about alpha), and it maps out to what I saw when I was picking which tournament I would enter (another option was chess, I chose algorithms instead). It's a way for whites to not judge based on the color of people's skins. And further in Freakonomics an Indian sociologist did some polls in housing projects, ended up not getting killed because while not African he was dark too, not black, like in a gray area. OK they considered him gray. So that's how he was privy to the economics of the street drug market, and the tournament aspect of it.
