just me: not ruach hakodesh, just fantasies of grandeur. these rabbonim dont realize, by claiming these things, they are saying they have nevuah, which puts them in one of three categories. a child, a woman, or a shoteh. as they are neither a woman or a child, that only leaves…. (which would explain their use penchant for knowing why calamities befall our nation)
personally i think the reason is because rabbonim are to busy banning concerts and other things, and not banning yeshivas that allow all types of nevalah to go on behind closed doors!
