popa- i think R chaim soloveitchik said it best- theyre not kashos; theyre tirutzim.
Zdad- lts of them. and the ones who dont are because they dont feel theres too much sakana in a bunch of self-hating crazies. if MO feels some level of threat they should also feel compelled to respond. which i also think is the reason no chareidi gedolim (not newspapers-i mean the manhigei hador) took a stand against weiss; they dont even have a chashash that their kehillos will be swayed- no threat- hence no reaction.
