I am not sure where you are getting your information. I don’t read the Wanderer or the Remnant, so I am not getting my information there.
What I do read is Our Sunday Visitor (which has had several articles on the matter) and The National Catholic Register, both of which are centrist rather than on the end of the spectrum that National Catholic Reporter, or the other end of the spectrum or the two first mentioned.
They are reporting on healthy, growing communities which are not “Latin Mass Order of XYZ” as you so pretentiously set out dismissively. Yes, they wear some form of habit; some a more formal one than others, but none of them seem ashamed of being identified as a processed religious.
And I don’t know - maybe you consider Franciscan and Dominican communities as “non mainstream”, but if you do, it tells me a whole lot of what you think. And they are orders which seem to have resolved that use of the Enneagram really is not consistent with 2,000 years of Christianity, and the LOTH is. Funny how that all works to the surface.
