The project is primarily a cultural center, with prayer space inside, not even technically a mosque (a mosque is, by definition, a building dedicated to worship). That said, I don't see why it would make a difference either way. Aside from zoning issues (which are non-issues, anyway), I can't think of any good reason to oppose the project. In fact, I don't think I've seen someone in the media give a single reason for opposing this project that wasn't ultimately based in ignorance and bigotry. That's not to say that everyone who opposes the project is a bigot, but that doesn't mean that they don't have opinions rooted in bigotry.
