In short, this article points to an instance where Herman Cain is being attacked by a pastor because on the surface it appears that he is taking an anti-First Amendment approach. I would tend to agree, if I only looked at the surface, and no deeper.
Let's look deeper, shall we?
It seems that there is quite a bit of information leaking which points to this mosque being the project of the Muslim Brotherhood. That group is not a religious group, but rather a political one, which would like to see a 'conservative' (in this case, read strict adherence) application of Sharia law. This is a major issue for any American.
Sharia law is about as far removed from the concept of individual liberty, and equality that we have established in this nation, and about as anti-American as it is possible for an organization to be. Additionally, the terror group Hamas is closely related to this group. The last thing we need in our country is a breeding ground for terrorists.
Beyond this, there is sufficient protesting and complaints from the residents of the area that they do not want this constructed in their neighborhood. While I'm a firm believer in private property, there is a point where you need to understand that your neighbors don't want your business there. And let's face it, if this is an entity related to the MB, this is no religious center, but rather a political one.
Were this to be a purely religious facility, with absolutely no ties to politics, or any attempt to muddy the local political waters with Sharia law, I would have no ground on which to stand. However, just look at the organization(s) backing it's construction, and pushing for it to be built. There's an old saying that suggests that following the money will lead you to the source of any activity. I think the same applies here.
