there's been similar issues in the UK. In Manchester, a church was knocked down to build a mosque. I read about this in the Daily Mail, so it was obviously full of 'DISRESPECTING OUR CULTURE INNIT!', but according to the article, few people still visited the church, although those that did were left out in the cold a bit. I guess you have to choose the lesser of two evils.
As to the Swiss minaret ban, I don't know much about it, but it does sound rather paranoid.
