It seems the parent is trying to imply that the grandparent is arguing that some immigrant races are good and others bad (hence his reference to US hispanics, asians, europeans, etc) even though the grandparent is very explicitly arguing that the best immigrants from India and China respectively go to the USA while the mediocre immigrants from those countries go to Canada (I'm not arguing for or against that claim, but I can understand how it is different than what the parent alleges).
