That is not true, light skin women, actually have it harder, in dating. Women who are more tan usually have an advantage. It is scientifically proven, man with light skin tone are more likely to attracted to women with dark skin tone and man with dark skin tone are more likely to attract to light skin tone, but man are more likely to attracted to those who are same skin color, in term of skin color, there are three groups, brown, yellow and red. brown is the African and people in certain parts of Middle East and Pacific islands and Australia, red is the Latino and native Americans, yellow is the whites (not including Latino) and Asian. Our traditional view of the existence of black, white and Asian race, is scientifically proven false. To be qualified as different race (scientific term is breed) require genetic mutation, but similar enough to keep on breeding and producing offspring and so on, so, two breed of dogs, their DNA isn't 100% the same, but are similar. There use to be other race of humans, but they all died out during the ice age, only our race exist, but we are capable of having multiple skin color and skin tone, amount some part of Africa, there are even those with blue or green skin, but they are very few in number. Light skin tone and dark skin tone require certain DNA opposite, and many are instictively attracted to opposite.
People of European heritage are either light red or light yellow. (Light red is Latino) Native American are dark red. Asians are dark yellow
However, currently, due to culture reason, most men from China, are not persuing white women, leaving only men from other South East asia nation such as Taiwan, Japan and Korea pursing white women. White men (pale yellow) on the other hand, are still pursing Asian woman (dark yellow). This also leads to why we are seen more couple of White men and Asian women, then vise verse.
As a result, in the west, been a white woman of light skin, actually disadvantage you, women who are Asian or have tan skin, would have a greater advantage, if a white woman with light skin, truly want to be advantage in dating, they would have to move to Asia (but not China), there are even men who only date white girls, there
