A Dinaric-Mediterranean Macho Touch?Dark hair is an ancestral trait (of little taxonomic value); no population is exclusively blond. A Northwestern European with dark hair does not have "Dinaric or Mediterranean hair"; he is manifesting part of normal Northwestern European variation.
It is no accident that the ideal type of White male beauty in the West never appears in a single racial type but rather as a combination of all three. Historically, the ideal type of an attractive White male has Nordic stature and skull with dark Dinaric or Mediterranean hair. No wonder that White women in the West are attracted to this combination, as embodied by films stars Antonio Banderas, Sean Connery, etc. Seldom is a pure Nordic male specimen viewed among White women as the epitome of male attractiveness. There are jokes in continental and southern Europe about blond-haired White males being “albinos” or “faggots.” Manliness, with a grain of machismo, has traditionally been associated with the Dinaric and Mediterranean subtypes.
The data I'm aware of indicate white women prefer blond hair to black hair in men and the proportion of women favoring men with blond hair is higher than the proportion of men with blond hair . The modal hair color preference of both white men and women is brown (probably not coincidentally the modal hair color of Northwestern Europeans).
Brad Pitt was "chosen by Empire as one of the 25 sexiest stars in film history. In addition, he has twice been named the Sexiest Man Alive by People in 1995 and 2000." See also: Robert Redford, Jude Law, Daniel Craig, etc.
As for why blond men are disproportionately cast as villains, Steve Sailer has written:
Exactly why Hollywood hates blond men almost as much as it loves blond women is not clear. Some have suggested complicated combinations of resentment and longing in regard to WASPs and/or Nordics.I don't think it's complicated or mysterious. It certainly can't be to Tomislav, assuming he possesses the slightest bit of self-awareness.
Relatedly, Tomislav might consider the possibility that jokes about Northern European men by people who look like him are not the best source of objective truth. For the record, Tom, there are jokes in America and northern Europe about southern European males being "greasy" or "faggots" (in addition to serious proposals).
It goes without saying that Northern European men best exemplify manliness as defined by Northern Europeans. Southern European men are typically viewed as lazy, dishonest, cowardly, and effeminate by contrast. I grant that, by southern European standards of manhood, the overwhelming majority of Northern European men are likely deficient in gold chains and body odor.
