Yeah, if you notice, I mentioned keeping the foreign-born population at a single digit of the total population to manage social risk. Anyway, I'm glad you conceded the point that Indians are not inherently stupid. Racism in all forms should be condemned but the point is that immigration is good for the economy and good for technological development. It's also if done well, good for the native people since everyone benefits from an expanding economy. Even if you desire for your ethnic group to maintain it's incumbent power, which for China, isn't really contestable, you can still have immigration that is good for the economy
California has middle-of-the-pack SAT scores and crimes rates about in line with the US as a whole. There isn't white flight. There are white people leaving for economic, not social reasons and there is still substantial in-migration of white people to California. And fwiw, Texas is also majority-minority and is the polar opposite of California. Florida is also moving towards being majority-minority, go tell me about hwo the minorities of Florida & Texas are going to cause a rebellion or whatever.
Nowhere did I say there aren't genetic differences between different racial groups in cognitive or behavioral traits. I don't care if it's racist according to the Western dogma you've inherited, it's also true. Take that crap to some Western forum, muh rayycsiissm won't play well here. I am a geneticist and have worked at (and invested more money than you can count) at the most advanced biotech & genomic companies on Earth and it's an open secret at all of them. It isn't even in contention among those at the top in their respective fields (in pop or behavioral genetics especially).
Of course nutty people like you like to believe genetic differences suddenly stop above the neck, because nature for some reason loves adhering to Western liberal coping mechanisms and wouldn't dare touch the brain, lest it offend your douchey limp-wristed sensibilities.
