There seems to be two different mindsets with these people.
Some probably wouldn't give a shit if the books were opened up to accept Irish and Jews; like Roy De Meo and Lucky Luciano.
And then there are those with a tribal attitude, like Vito Genovese, who whined about Luciano collaborating with all those Jews back in the olden days.
I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
