first of all marriage of orthodox jews should be based of love
there's nothing wrong with a black jew , common , that is a wierd quastion
Go (i'm saying this in sake of parallelism , not actually telling u to go somewhere but israel) to stay in ethiopia for 2000 years and tell youre offsprings to retrun after such a long time , They will be black in skin!
all jews are jews , there is no difference , and i saw very nice looking ethiopyan jewish women , So , "tafsik levalbel ba moach" , as we say in hebrew hehehe
and even for the sake of the arguement , there are ugly white gentiles female's as there are good looking black gentile females (and vice versa), but u should marry neither (unless they bacame jewish) because youre jewish and suppose to marry only a jewish girl
