The Baal Teshuva Movement

 BTW one of the saddest respondents I encountered was Rav Ephraim Buchwald, who was a leader at YU’s TLS and then founded and led National Jewish Outreach Professionals. I know, like and respect him very much. This is what he wrote to me:   

The rise and decline of the Baal Teshuva movement, particularly the rise and decline of the non-Orthodox synagogues in the U.S. Conservative and Reform synagogues were the primary feeders of the Baal Teshuva movement. With their collapse, the religious return of their youth has ceased. With few exceptions, the Baal Teshuva movement has sadly ended.
