It is worthwhile noting that time has proven correct the rabbonim who banned Lipa. In recent years he has turned out to publicly be mevaze talmidei chachomim and gedolim on a regular basis, aside from the drivel he produces.
The rabbonim had the foresight most of us do not posses.
The same has proven true with rabbonim who banned Slifkin’s book. He, too, today regularly is mevaze talmidei chachomim on a full-time basis.
