According to the opinion of the Satmar Dayanim even if one does tshuva, they still cannot be let back in and forgiven. Where in yiddishkeite do we have an idea that even if one does tshuva that hashem doesnt forgive (We are talking about Bein Adom L’Makom not Bein Adom L’Chavero) Isnt that the idea of aseret Ymei TSHUVA, isnt that the idea of Rosh Hashana and Yom Kippur that we can do tshuva.
Are they creating a chumra even hashem doesnt want?
