I thought it was because there fat, and unwanted 
historically its true that there was a cartain trashy, fat, unedcuated "type" of white girl that went mudsharking
fat bitches that no white guy would think was particularly pretty, but a black guy would treat like a "10"............cause he was so happy to have a white bitch, ANY white bitch
but currently......the truth of the matter is young white women are told (by the jew media) from a very young age now that interracial dating is both acceptable and cool.......think of these MTV shows, the kardashians, ect.
so anymore, no, its not just fat piggies looking to be treated like beauty queens...........EVERYWH
ERE i go, i see HOT white women hanging on black guy, girls that are 7s, 8s, 9,s ..........that ANY white guy would go after
you see more of it in some places then others, but it really is everywhere now
but the only reason it is becoming acceptable, is because the jew-controlled-media wants to make it acceptable, and pollute the white race...........
these same jews who run these media divisions who appear so "progressive" and "liberal" are surprisingly not so liberal when it comes to their own sons and dautghters
anyone who has been around jews , knows how militant they are that their own children only date and marry jews to preserve the bloodline and numbers.........they know from a young age that marry out side of judism means outright excommunication
