I've seen AW admitting they want to have a white SO as they see Eurasian kids as spectacularly beautiful instead of finding WM extremely attractive. Honestly, I think it's just an excuse they come up with. That fact they find Eurasians spectacularly beautiful imply they find white/whitish features more attractive than Asian ones and this probably means they do find WM more attractive too. Sure, you can argue they want Eurasian daughters and maybe they think Caucasian features only look good in females but not men, but honestly, most women will not date men from a certain race they're not attracted to just because they want their kids to look in a particular way.
Also, even if these AW marry an AM, it's not "impossible" for them to have white/whitish-looking kids. If these AW live in the West, they can find a white sperm donor for Eurasian kids, although I understand the AM will probably object to that so most bananarangs married to AM usually have Asian kids or no kids at all. They can also consider adopting white kids, but I understand it's hard for Asian families to adopt white kids due to racism.
