Religious symbols should be visible in public space, in a dignified and non-provocative manner. Christmas trees here, Jewish menorahs there and, further along, a minaret - these symbols represent human life in all its diversity.

Muslims must speak out and explain who they are, what they believe in, what they stand for, what is the meaning of their life. They must have the courage to denounce what is said and done by certain Muslims in the name of their religion.
