== Quasiracial/religious classifications == 

 There is certainly an ethnic/religious angle here, but only because Madoff made something out of it, and exploited it. It doesn't seem necessary to me to classify his family in any given way in the introduction. As for the way he made others trust him because of their shared religion and of how they saw his origins - it is good that that is being treated, and perhaps it can be treated at greater length and more explicitly. 

 It's also a good thing that there are no tags of the "X Jew" and "Jewish X" at the bottom. At the same time, it seems to me that such tags are grossly overused all over wikipedia. If we are going to delete them from articles on grossly objectionable characters, and insert them at the bottom of articles on very laudable individuals, then we are introducing a rather gross kind of systemic bias into Wikipedia.
