The jewish one you can. Jewish religion is passed on maternally, so technically Bill Maher is a jew. Whether he practices Judiasm or not.
Can you respond to my question posed in post #7? How does one trace the purity of the mother’s Jewishness? Can a mother who converted to Judaism pass on the Jewish religion to her offspring? Is it religion or ethnicity that determines the purity of the Jewishness? Are their two classes of Jews, i.e, one who are pure and inherited the religion and the other who volutarily became Jews?
