Specifically looking at the Smithsonian article, they don't even mention xenophobia until the last sentence. What they're talking about is instinctive preference for other creatures which the baby identifies with, and in the research the article cites there isn't any direct correlation to race. They talk about food preference — something superficial. There was no research cited to indicate whether the behavior extends to racial distinction, so your using this research to back up your claim that "babies of about the same age as the ones shown in Obama's tweet already display instinctive xenophobia" is intellectually dishonest at best. And I ignored the Independent article because they're known to be poor at in-depth reporting.
