They've been presented as unattractive by the media for a very long time, its obviously going to have an impact on your mentality.
I don't know about that, black women have had more representation in media than Arab, Desi and Asian women, and still most men would choose the latter group over them. Horn African women have higher cheekbones and button noses, which is the antithesis of black women who tend to have broad noses and strong brows, it's in their features; it's just not attractive to me.
