Not to downplay your article but there is no reason why a Noahide cannot study Kabbalah and have Kabbalistic rituals as well.

Esteemed Terry and Breslev Israel We, from the "a-fe-original–noaismo.info" Site (The Original Faith: Noahism.info, in Portuguese), fully agree with you. Many of our publications (which are, almost all, translations of other publications in English and Spanish) deal exactly with this point-that spirituality is not religion and religion is not spirituality. And we have insisted on the fact that while serving God (and praying) is a universal issue, Jewish rituals are a particular matter, proper to the Jews, yes, exclusive to the Jews. We constantly reinforce the fact that Jewish rituals are (obviously) part of Judaism, not of Noahism, and that Jewish rituals are (obviously) only of the Jews. It is, in fact, such a simple thing-so easy to understand-but people (some) really insist on not wanting to see, and accepting the Truth. If people are wanting the Jewish rituals, let them convert. But there are those who do not accept them (because they were not ordained over them) and are happy just like that; this is the true Bnei Noach Movement. A recent example of what we have said is here: https://a-fe-original–noaismo.info/o-rebe-diz-nao-a-judaizacao-de-bnei-noach/
