Does Stein pay 10% of his wages every year to go into an organization that spends millions of dollars online, in publishing, in translating into hundreds the languages, the ideas that...
...Christianity is a false church? (implied; Lds doctrine & covenants 1:30);
...All Christians are "apostates" and spiritual or literal descendents of "apostates"? [standard Mormon doctrine -- no different Muslims who believe Christians are "infidels"];
...ALL (not some) Christian creeds are an "abomination" to his God?; (Pearl of Great Price)
...ALL (not some) Christian professors are "corrupt"? *(Pearl of Great Price)
...that ALL non-"Lamb" churches (those that aren't Mormon) are under the banner of the Church of Satan? (Book of Mormon, 1 Nephi 14:9-10)
See, that's the big difference.
If Stein says he adheres to the Old Testament, then that's not offensive to Christians.
If Stein says 10% of his income goes to promote the Old Testament, that's not offensive to Christians.
If Beck says he adheres to his "standard works" of Mormon "scriptures" -- the Doctrine & Covenants, the Pearl of Great Price, and the Book of Mormon, then, yes, that's offensive to Christians.
If Beck has 10% of his income going to promote the above, and tithing Mormons do, then yes, that's offensive to Christians.
