This Race Doctor Probably Hopes That In The Year 3000 99,9% Of Cultures And Native Peoples Are Gone.

Currently White-Hispanic pairings regardless of gender are most likely to end in divorce (Source: Wikipedia - Interracial marriage in the United States).

Quoting the article:
"In the past, the study said, we largely relied on real-life social networks to meet our mates — friends of friends, colleagues, and neighbors — meaning we largely dated people like ourselves. Now, as we open our dating pool to strangers, the pool of potential mates has become more diverse, and the online dating world is “benefiting exponentially,” said dating coach Meredith Golden."

“We don’t always fall in love with our clone so a wider dating net, be it outside of race and ethnicity or tapping into a large LGBTQ pool creates happy unions,” she said. A rise of interracial couples can alleviate prejudice and racism in society, studies show, and usher in a multiracial future."
