I have actually had a pretty good experience with white women as a whole, it is not that I cannot get a blonde or redhead. Now just to note, I am a minority but handsome compared to most guys of my race (Indian/South Asian).
What I notice is that while I have to proactively pursue blondes and to a degree redheads (who are a small number of the population anyways), I notice that dark haired white women (Italian, Jewish and Eastern European) and to a lesser degree brunette white women pursue me more aggressively. Like I am talking meeting me and putting their arms around me, flirting with me more, sending me sexual messages on dating apps and making it clear they want to smash. I don't have this experience with blondes or redheads.
It kind of makes me wonder about the whole "opposites attract" theory, apparently I am supposed to have this experience with blondes and gingers while brunettes are supposed to be very meh towards me.
