Guter Yid; I just read your comment (Among others.) Even though I did not read ALL the other posts. Just enhancing the points that you bring forward.
a) Your impression of “Zahavasdad”‘s depth of knowledge & connection to the way of Torah is the same as mine.
b) The general consensus, even among the vast majority of the OTD community (And there is a sizable one out there.) is, that the memoir by Deborah Feldman a/k/a Sarah’leh Berkovic is substantially untrue, and has done more harm than good, even to their cause.
c) It is not driven by anger or the perception of hurt feelings. Rather by opportunism.
