While White-Male-Asian-Female couples have been common place for years, Asian-Male-White-Female couples are still rare.
People who support or condone race-mixing commonly argue that White girls are degenerate whores and depraved feminists eager to screw over men in divorce.
You can't call out black men for going after White women if you condone white men chasing Asians or even go after them yourself.
If you truly believe that every race has a right to exist, and many here profess just that—then the first step is stopping race-mixing where you have the ability.
Some researchers spoke frankly about this subject (probably because they assumed shitlords would never find it) and produced what may be the most based quote in a serious academic article ever: "Nonwhite daters gain status by dating white.
Whites, on the other hand, have little to gain by dating minorities." That situation doesn’t make for a very healthy relationship.
In contrast, Asian girls are portrayed as traditional, virtuous, and loyal.
