A lot of Asian or white supremacists who go out to their ways to stop or discourage interracial couples, particularly WMAF go about lookism. This is an example of an Asian guy making a comic where the white guy is very below average but still did score with a lot of Asian girls, a sentiment they feel in the couple the girl is much better looking than the guy

Lots of cope in it obviously, but it's how it goes for them. When they can't insult appearance, they go for the "you're brainwashed, you hate yourself" and so forth.

In few words, if the white guy doesn't look like this, then he's never good enough to get over an Asian man
