I figure atheism (more likely, agnosticism) would be a step in the right direction from following a false god. Someone can evangelize them later.
The Giordano-Bruno-Foundation (the article mistyped Giordana), is a German secular-humanist organisation named after the medieval monk Giordano Bruno, who was killed as a heretic. They consist mainly of Professors, writers and scholars not only critical of the Roman Catholic and Lutheran Church in Germany, but also the negative influence of Multiculturalism and Islam. They mainly engage in scientific research and studies regarding religion and philosophy.
