In her book "the last Jews of Kerala" Edna Fernandes describes the life of the remaining Jews living in Kerala. She unfortunately places far too much emphasis on the question of colour but when she came to Israel to talk to the jewish population that immigrated to Israel from Kerala she neglects to interview any member of the white group - who,by the way settled more in the centre of the country and did not "make the desert bloom" as she puts it. I, personally, do not know any of these "white" jews but do know many of the "black" jews that immigrated from Kerala as they live near me in the Negev and they are "the salt of the earth". I have never heard them complain of any type of colour bar either here or in their past life in Kerala (although they will tell you that it existed if you question them)and they are very industrious people.
Edna Fernandes should also be more careful if she wants to intersperse her narrative with hebrew words by making sure that she really does understand them and the difference between singular and plural in Hebrew.
