There's (societally) a lot of conflation of religious and ethnic identity. Sometimes, like with Judaism, it's hard to separate, partly because we use the same word to mean both the ethnic/identity group and the faith group (Jewish). I didn't know there was such a thing as an atheist Jew until I met one a dozen years ago (because, like much of society at large, I conflated them into both religion and cultural identity). [Is ethnic the right term to use? What makes an ethnic group, anyway? Shared culture? Shared roots? Societally, we seem to use ethnic and racial (and sometimes cultural) interchangeably, which gets confusing.]

Anyway, I think the point/question I was trying to make in the earlier comment was that he may not have even had a Jewish [religious] identity or just a tenuous cultural connection. But I forgot that scene about his most beautiful memory (being distracted by how much Erik & Charles should really have been doing it).
