Reihan is right, the proudly multiracial ought not to take offense at being asked about their race. That said, what Reihan misses is that Geetha Lakshminarayanan's multiracial pride might be something of a defense mechanism, and might have come out of her being constantly asked what she is. Timing is everything--was she first bugged about being multiracial or proud of it? I have no experience being multiracial, but I have been referred to as exotic, which led not so much to an existential crisis as to a realization that I'd probably get more attention of a certain kind in the Midwest than in certain parts of NYC, where every other person on the street looks just like me.
Reihan also discusses and debunks the "quasi-narcissism" of many upper middle class parents, one of whom is Asian and the other non-Asian:
"Our babies are sooooo cute." For real, yo, it's not that cool to be an upper-middle-class non-Asian person marrying an upper-middle-class Asian person. Seriously. No medals for you. Maybe next time. Call me when you marry someone from a Papuan cargo cult and ritually scar your toddlers with elaborate patterns that resemble the cheesecake murals emblazoned across WWII-era bombers like the Enola Gay. Then we'll talk.
This I'm not entirely sure of. No medals for you if you are a white man and your wife is Asian, but pairings are less common the other way around, so perhaps a few medals can be allocated.
