Also while our churces have to sell use of their churces to attach mobile phone antennas to stay open, mosques get subsidized. In Rotterdam a condemned building was bought by the local government, for 1.82 million dollar (a lot more than it's value). Then they subsidised the mosque (called Mevlana) for 2.43 million dollar while the people only had to raise 1.82 million dollar themselves.
