I was recently asked by someone I very much respect to address "the" question. So I started to write the answer in a post... about five times without any luck. The "Why does a 20-something join a Reform Congregation" question.
Typically, at some point in my work on this project, my wife will lean over my shoulder and ask me, in her own style, “So. How are the Jews this year?” Some years that is a difficult question to answer. This year the answer is clear: The Jews are afraid.
