how is this any different than the google/apple ads in theaters pushing freakshow social agenda images?
It is not an offensive ad, it is just an people praying.
It's no different, legally. If it stands, than it would be equally valid to have an Iman reciting the Quran before "Spectre"; or a Christian Scientist asserting we have no arms and legs before "Star Wars"; or an Atheist proclaiming there is no (Christian) God before the latest Disney offering; or a neo pagan extolling the virtues of Gaia...
Get the "picture"?
I'm all in favor of Christian witness, but this is not the way to do it.
