The white supremacists on the far right have “yellow fever” — an Asian woman fetish. It’s a confusing mix.

Andrew Anglin, the founder of the neo-Nazi website The Daily Stormer, once posted a video of himself with a Filipina he called “my jailbait girlfriend,” the young couple flirting as they sauntered through a megamall in the Philippines. Richard Spencer, a white nationalist, has dated a series of Asian-American women, according to one of his ex-girlfriends. (Mr. Spencer insists that it was before he embraced white nationalism.)

The right-wing agitator Mike Cernovich, the writer John Derbyshire and an alt-right figure named Kyle Chapman (so notorious for swinging a lead-filled stick at Trump opponents at a protest in Berkeley, Calif., that he is now a meme) are all married to women of Asian descent. As a commenter wrote on an alt-right forum, “exclusively” dating Asian women is practically a “white-nationalist rite of passage.”

In November 2016, a photo of Tila Tequila giving a Nazi salute went viral. Ms. Tequila is the Vietnamese-American star of the short-lived MTV reality show “A Shot at Love With Tila Tequila,” and she was saluting at a dinner the night before the conference of Richard Spencer’s white-supremacist think tank, the National Policy Institute. At the conference, Mr. Spencer had reminded attendees that America was a “white country designed for ourselves and our posterity.”

Maybe it makes sense that the alt-right is so confused: On a neo-Nazi news site, a user asked advice on whether he could be a white nationalist if he slept with East Asian women, and he received dozens of spirited responses from both sides. But the white-supremacist Asian fetish is no contradiction.  ...
