Why are southeast Asian and Asian pacific women looked down upon?

rosesofsarahhhh
I stumbled upon a news website of Swedish/Danish men going for southeast Asian women. Most of the comments and answers on quora say that "those who go for southeast Asian women are 'losers' and 'of low standards'".

For people in especially southeast asia and asia pacific , if your spouse is a caucasian/white/european man or woman, that is regarded as high class event.

Most of the comments I see are those who say that" white men who go for southeast Asian /asia pacific women are losers who couldn't get any high class caucasian women. "

You can go for Japanese /chinese/Koreans, indians, middle eastern or europeans, black, and still be regarded as equal social standing with the spouse but southeast Asian women? For them, that's really low class. They really look down on southeast Asian women.
I have heard more than once saying that southeast Asian women are far inferior than caucasian women because of physical looks.
But Why?

Addition : i am also deeply saddened over the issue and common thought as I am also a southeast Asian. It seems that as if globally, there is a racial/origin hierarchy. They see southeast Asian women seldomly as toys and things. You don't see much movement for southeast Asian women or Asian pacific. Or representation of those women in modern world. Southeast Asian are told that they are never enough and can never be as the same as caucasian women, look-wise and social - wise.
