Dear Rabbi, are there binding details attached to the Noahide commandments? For example, if a Noahide has an interpretation about whether he is transgressing a Noahide commandment in a specific situation, are there things that restrict his room for interpretation? If there are such details, what if a Noahide does not follow them, because he does not believe that he has transgressed a Noahide commandment? Can he loose the status of a righteous Gentile and the eternal reward? Thank you in advance.

Just as Jews have many binding details which are obligatory, so do Noachides, and yes, this can lead to their losing their status as Noachides. For a given particular issue, one must give all of the details.
