Nah, I don't see the need for so much venom. This is a traditional American story where a family actually takes a couple generations to sort out whether they become fully American. It's not like any of these women took an oath and betrayed it, because we don't require any oaths from stateside-born citizens who hold constitutional citizenship. Hate the game (
alien of extraordinary ability), not the players, like
Eileen Gu's mother.
Once upon a time, Americans placed their loyalty to their state over loyalty to the nation, and, similarly, Chinese traditionally place loyalty to family over everything else (the Zhu clan, the Gu clan, etc.). Modern China, with clan loyalty being atomized by the great migration to the factory cities, is newly becoming nationalistic in the same way we are. How the Chinese-American diaspora community copes remains to be seen. The decisions of these athletes are mostly driven by branding opportunities -- which national venue offers more endorsement money, "Nothing personal."
LOL, in other news, another 'alien of extraordinary ability', Justin Bieber, a Canadian who swore he'd never become an American citizen, is supposedly studying to gain US citizenship. Meet his American wife, Hailey Bieber, citizenship-tussle victor, submission by traditional wrestling holds:
