No one who supports Glenn Beck and his rallies ever says "the Torah says" or "the halachah says". They all say "I feel" or "I think". Torah true Jews base their thoughts and actions on halachah so here is the halachah.
Lets start with Jews calling Beck a righteous gentile. He is not.
The Rambam says:
Anyone who accepts upon himself the fulfillment of these Seven mitzvoth and is precise in their observance is considered one of the Pious among the Gentiles and will merit a share in the world to Come. This applies only when he accepts them and fulfills them because the Holy One, blessed be He, commanded them in the torah and informed us through Moses, our teacher, that even previously, Noah's descendents were commanded to fulfill them. However, if he fulfills them out of intellectual conviction,he is not a resident alien, nor of the Pious among the Gentiles, nor of their wise men.**(Hilchot Melachim U'Milchamoteihem 8:11)
Any xian will tell you they are not "under the law" meaning Hashem doesn't "command" them to fulfill any mitzvot. Any mitzvah they do, they will tell you, is because their false god yeshu did them or told his followers to do them.
**this principal may be derived from the Mishnah's statement (Sanhedrin 90a) that Bilaam will not receive a share in the world to come.
Bilaam was the prophet of the goyim, he believed in Hashem and Hashem spoke to him. He even "blessed Israel" three times with blessings. Yet according to our Sages he was not a righteous gentile nor does he have a place in the world to come.
Mormon's believe there are many gods and each person can choose which to worship, which is why Beck can say,
"Things will be okay if you live your life in accordance with the God of your understanding".
Mormon's also believe that every human being has the capability to reach godhood. This makes Beck an idolator.
In Sefer HaMitzvot it is written,
It is a negative commandment
213.not to turn astray after idol-worship, neither in thought nor in word, nor even by watching
426.to show no mercy to idol-worshippers
(that we should have no kind feelings for those who worship idols, and nothing about them should be good or pleasing in our eyes; in other words, we should remove far from our mind, and it should not[ever] arise in our speech, that there could be anything of value in one who worships in idolatry, and he should find no grace or favor in our eyes)
436.the precept to destroy an idol and all objects in its service
(at the root of the lies the purpose of eradicating the name of idolatry and every memory of it from the world)
