You see thirsty outliers whenever you see that. Pretty much all the fit black dudes I know who date white women made sure their women are normal or fit. The problem is fat white girls are easy and culturally many black guys get the desire to explore other races especially white girls. Why don't they date normal white women then? Some do, but others go for the low hanging fruit so they can get their dick wet constantly. If I had a dollar for all the random white girls normal and fat who wanted some "BBC" I could pay off my student loans.
