I appear to be missing your point or you are beating around the bush. What relevance do the number of blacks in Hollywood have to do with this discussion? Let's be explicit -- are you saying there are not many secular Jews in the film industry?
Second before you nit pick me read my whole post of which the point you are attacking plays a quite peripheral role.
What percentage of the 164,000 to 226,000 directly employed in the industry are Jews and what percentage are other groups ?
