IMO, I have seen examples of beautiful people from most ethnic and "racial" groups- Perhaps beautiful by different standards, but all beautiful. And I have seen less attractive examples , again from all groups.

I understand where you are seeing the "Blue eyed blonde" ideal, but I do not believe that it has ever represented the majority of male viewpoints in the Western culture(s). And since those cultures have been dominated by males at least up into the 1980s, I fail to see

"that blond haired, blue eyed White women has been the foremost standard of physical beauty in the USA and "perhaps in other Western countries", "

I do agree that the media has presented that view: it is just not reflected in the culture as a whole. ( besides, you left out stright haired, properly shaped nose and lips, and hour-glass figure- ALL presented by the media as the ideal.).
