BERLIN, Germany (Reuters) — The first rabbi to be ordained in Germany since the Holocaust is so worried about being identified as a Jew that he often wears a baseball hat over his skull cap.

“It’s a fact — it isn’t smart to display I’m Jewish. This is a problem and we have to face it,” German-born Daniel Alter, 47, told Reuters in an interview.

He is worried about neo-Nazi attacks and says anti-Semitism in Germany — still tortured by memories of the Holocaust in which Nazis wiped out 6 million Jews — puts the growth of Jewish communities here at risk.

As a Jew he feels unsafe in several German cities, not all in former communist east Germany where the far-right National Democratic Party (NPD) has made electoral gains recently.

Alter, whose father survived Auschwitz concentration camp, dismissed talk in the German media of a possible blossoming of Jewish life in Germany.
