Low says in the article that the term 'born again Chinese' comes from scholar Liew Kai Khiun: "to describe people of Chinese descent living outside of China (especially Singapore and Malaysia) who identify strongly with, and hold blindly optimistic views about, China."
"The term draws parallels with the “born-again” Christian phenomenon. Just as born-again Christians aren’t usually born Christian, born-again Chinese (BACs) may not be born Chinese or raised in a Chinese-speaking environment. Being educated in English, BACs usually have a poor command of the Chinese language and have little understanding of Chinese history and literature."
"Yet, like born-again Christians who are often more “public” about their faith than born Christians, BACs can be shriller and more strident than people who are born Chinese in defending their “motherland”.
All of this is very precise.
