At the risk of sounding like a “representation matters” lib, there’s basically zero depiction of Asian men in westoid media as positive role models or attractive partners. Even today it’s incredibly rare to see any movies or TV with Asian male protagonists, and the Asian guy “getting the girl” is practically non-existent.

Add onto that a consistent trend of emasculated Asian men as weak, short, and feminine. This is not unlike how a lot of media and people still think of black women as aggressive and over masculine, at least to my understanding and hearing it from a few black women.

Lastly, there’s still this idea that sexual racism is acceptable. Like if someone says “I don’t want to date <race>” it’s still broadly seen as a legitimate personal choice. Compare with someone saying “I don’t want to work with <race>” or “I don’t want to be friends with <race>”.
