Pro-Reli Group Seeks Mandatory Ethics or Religion Instruction

BERLIN - APRIL 18: The brodcast tower at Alexanderplatz is visible behind a sign sponsored by the German left-wing Die Linke political part urging Berliners to vote no in an upcoming city-wide referendum on whether to introduce a compulsory choice between religion and ethics classes in Berlin schools on April 18, 2009 in Berlin, Germany. The grass-roots group Pro-Reli has instigated the referendum, and the measure would change the current system, whereby ethics classes are mandatory and religion classes are voluntary.
