Why do people promote interracial dating so much in the black community?

I don't hear people promote interracial dating nearly as much as they do in the black community. I wonder why is that? Why don't I hear them promoting interracial dating in the white community, Latina community, Indian community, Chinese community, etc...? I swear there is an hidden agenda, well at least that's why I think. SN: I don't have anything against interracial dating, btw.
