Stan, I wouldn’t read much into that story (at least judging by the link you supply). There only appear to be a handful of (rather disreputable) protestors opposed to the mosque, and all the main political parties in Cologne support it. So long as the construction is in accord with local zoning rules, and did not benefit from any special dispensations that support seems fair enough. I’d be interested, however, to know the source of funding for the mosque’s construction. If any of it comes from countries where there are restrictions specifically designed to stop the building of new churches, that would, I think, raise some rather interesting questions.
