Awful, simply awful. The atheist who returns to the town after 20 years, seems like an embittered and angry man, out on a personal vendetta against the heroic Christian mayor.The premise is that the mayor is building (and using some city funds) to build a stand outside of the town's city hall, for Christmas. There will be Christian decorations displayed along with more secular Christmas decorations. So this evil atheist type files an injunction to stop work on this stand.
Now, atheists aren't the only people who support keeping government and religion untangled, many Christians (though usually not evangelical types) also favor that. Atheists aren't out on personal vendettas against some Christian mayor or politician when we do so. Also, the "Merry Christmas" banner is moved because of this injunction. Frankly, no atheist has ever objected to a "Merry Christmas" sign, even in front of a courthouse.
In fact, I don't know if any church/state or atheist group would even object to this stand, unless it solely has Christian symbols. Atheists just want neutrality or at least, an open forum. Have Christian symbols such as a nativity scene, fine, but allow a display of the Flying Spaghetti Monster.
The Christian mayor in one scene recites the free exercise clause of religion, which for some reason makes this evil atheist type, say touché. That seems to imply the atheist knows he is violating the free exercise rights of the residents, but there is of course no free exercise right to have the government put up a display, even if not centered around Christian images solely.
This movie was produced by people who seem to have never met an actual atheist in their lives. Full of fear and straw man. If I could give a negative star, I would.
