Yankel berel, it is encouraging to see an haskama from Rabbi Feldman for Dr Berger’s book.
I think that most rabbonim do not know that there are Lubavitche that are engaged in idol worship. They just know that some Lubavitchers believe their rebbe is alive, but they have no clue that they worship him like an idol. Also, because it’s so bizarre to believe that a person who died is physically alive they believe it’s only a fringe group of Lubavitche that believe in that.
The real rabbonim I know do not watch Chabad youtube channels nor do read Chabad articles online. The modern “rabbis” who “love everyone” regardless of what they do and believe in, don’t care.
I hope rabbonim become aware of what is going on. I’d like to think they would care enough about kavod shamayim to protest the avodah zura that is going on.
