E = ethnic. Just be ethnic, nonwhite halo. Based on the universal idea the women enjoy foreign men, and that media and society and those who run it push nonwhite men on white women to destroy white societies. Virtue signalling can be involved from the woman's point of view. Don't know where you live, but in the midwest USA, the average white woman doesn't consider hew own men as sexual objects unless your the stereotypical chad, while she has been convinced by her friends, her media consumption (esp. social media), and by her own genetics to be conquered by men from other country that colored men are the only fit for her.
Most statistics used by JBW pushers don't answer the question of ATTRACTION or "CASUAL" SEX (usually marriage or relationships are used, which is unfortunately a bad meter of these things, you see how marriage is in 2020 for most), and often are all encompassing when it comes to age. On top of that, most stats are in controlled studies OR in online mediums, which completely avoid the method on which most JBE is run - in NT social circles in person.
