Moreover, are you trying to tell me that Jews and Noachides (whoever *they* are) are actively declaring Christianity "a false religion"? Can you name names? And are these people lecturing Christians that their faith is "unauthorized by the Torah."?
After all this, state your point. Thanks.

...24. In accord with the Seven Universal Commandments, man is enjoined against creating any religion based on his own intellect. He either develops religion based on these Divine Laws or becomes a righteous proselyte, a Jew, and accepts all 613 commandments of the Torah...
Judaism means that Jews follow the 613 commandments and Gentiles follow the Seven Laws of Noah or the Noachide laws. They include a command to establish fair courts to enforce these six prohibitions:
idolatry
blasphemy
sexual immorality
blood-shed
robbery
a limb torn from a living animal.
The belief in the divinity of Jesus would be regarded as Idolatry.
