"It is only the icchantikas, or persons of incorrigible disbelief, those who slander the Law, and those who pretend to be foremost in observing the precepts who cannot be forgiven." -- Nichiren
Even were SGI to apologize and sincerely repent of their errors, I could never accept it. On the contrary, they not only show no contrition but boast that they are the only group of believers upholding the Nichiren faith. They persist in their erroneous doctrines and proclaim that that they are foremost in upholding the precepts through their piddling acts of charity.
