It's a situation that "enlightened black opinion" doesn't approve of - she's just sounding a note of sympathy with her "sistas" who have seen a large number of higher quality black men go off to date and marry white women.
Nothing sadder than being around a bunch of bitter black woman complaining that”these white women are stealing our men”
Yet,like the song goes,”He would never have left you,had you not drove him away”.
