I don't mind Jewish people, at all, 
I'd  rather have one intelligent, educated Jew, than half of dozen "My Ten Cents ."

Why is Judaism passed down through the mother?  The reason it is passed down through the maternal line is not just because it is easier to identify who your mother is. It is because the soul identity is more directly shaped by the mother than the father. Ivanka's  mother -Ivana - was not Jewish, neither is Donald. She married into a Jewish family. Nothing wrong with that.
