OP, it's really simple. The fair Caucasian girls swoon over you because media and hear-say brainwashed them to hate their own phenotype because men of their own are supposedly unmanly. I look like a Russian wife-beater from the 50s (fair skin, Slavic face, blonde hair and blue eyes) so girls who usually have a darker complexion like Latinas, Mediterraneans, Middle Eastern, Indian and Turkish give me an easy time while girls who look like me make it insanely difficult for me.
Darker girls associate fair-skinned men as noble, gentleman-like, hard-working and not prone to beating them, something men in their respective cultures tend to be not, or at least they believe so. These girls tend to behave way more feminine than what I am used from my "own kind", so I'm not complaining, but I wish more of them would be feminine and not such sloots so I could wife one up because I want my children to look like me.
It all boils down to daddy issues and rebelliousness: if they hate their fathers, they want to be with a man who at least looks-wise doesn't remind them of their dad. If they love their fathers they want to be with a man who resembles their fathers, also looks-wise.
Rationally, I know it would be best for me to be with a fair-skinned woman but I am kind of traumatized by the many bad experiences I have with them; so emotionally I am repulsed by them. With darker girls it's the other way around: rationally, it wouldn't be the smartest idea to get together with one of them, but with them I have very good experiences and memories and they all have been emotionally nourishing to me as I was to them.
I'm ultra-white to the point you can see my entire circulatory system through my skin, with blonde hair and blue eyes, and I get the best treatment from black girls, Asians, and latinas by far, especially black girls and SE Asians.
The only girls I've noticed being particularly rude to me though are members of the neon hair brigade but I think they're just rude to everyone. Maybe I get it worse because I fall into all of the categories they consider evil at once though.
These neon-hair girls are just envious because you have natural blonde hair. I detest their choice to make a joke out of the true beauty of blonde hair.
