Mormons are as anti-Catholic (and racist) as it comes outside of Seventh Day Adventism, but have been toning it down in recent years to try to minimize their differences with Christianity, and have toned down many of their crazier doctrines and practices (e.g. those taken wholesale from Masonic ceremonies, the Heavenly Mother, the Adam-God doctrine, the Eternal Progression) while just “not commenting” on some, so they can be plausibly denied while the parishioners still believe in them (such as the belief that God the Father has a physical body and came down and committed adultery with the Blessed Virgin while she was betrothed to Joseph in order to conceive Jesus, anti-Catholicism), and weaselling around on others (Tritheism).
Just check out any original copy of the “Book of Mormon” with the original “Book of Covenants” (new editions are altered to remove racist and anti-Catholic overtones, but even modern BoMs and Doctrines and Covenants and Books of Abraham aren’t lacking in that department), changes in the Temple endowment ceremony (which used to show a Protestant pastor and a Catholic priest as agents of the Devil and Whore of Babylon, and are drawn straight from Masonism), or a copy of Mormon Doctrine by former General Authority Bruce McConkie, who’s just about as revered as anyone beyond Joseph Smith, Jr. (the “Prophet” who has so many parallels to the other false prophet, Muhammad, that it’s beyond ironic), Brigham Young or Joseph Fielding Smith gets in Mormonism (McConkie is the guy who edited the KJV “Mormon Edition” published by the LDS).
It’s even more ironic that the Mormon church is apostate by its own criteria, but changes slowly enough to attempt to keep its rank-and-file from realizing it and becoming Christians.
On topic: the film is anti-Catholic by repeating constant tropes of falsehood about the Church and the Bible, etc. that are used as mainstays by Jack Chick types.
