I believe in the right to own property, and the right to do whatever you like in that property as long as it isn't against the law. So no, I don't think churches should be banned anymore than mosques should be banned, or what people read, or what people wear, etc.
Besides, if you banned churches "as they exist today" all you'd have is churches springing up in new places, with new themes, new ideas, etc. If enough people want something, they will work hard to make sure they get it. Since churches still exist, it is clear that people still want them (or else they would have been torn down eons ago).
All you are doing is putting your own personal feelings above that of society; something that rarely leads to anything good.
