Reasons the Asian sisters might not want to hook up with an Asian man who dated outside his ethnicity is the same as Black sisters who resent Black men. The white people drive the paradigm on what is considered beautiful. Naturally, they're going to promote their women. Asian men who date white girls can be seen as buying into the hype. It's the same as when an Asian lady goes for the white man. One might say she is seeking social status and of course the white man is going to have more of it because his people drive the paradigm on what is considered powerful, successful, attractive. This is why Asian men are always considered the least attractive by women of any color. The Asian man has always been painted to be weaker, smaller, nerdy, and/or even untrustworthy.
