It was aggravating and disappointing that after I spent so much time and effort to join the yeshiva world  to discover the religous world that surrounds the great Litvak yeshivot [based on the gGra] to  be morally challenged. But I do not mean to exonerate the great yeshivot either. -they did a great evil by ignoring the letter of excommunication signed by the Gra. This left the door open for the Sitra Achra [Dark Side] to enter even into the great yeshivot.
