“I find it difficult to beleive that would happen in an Ashkenazic shul.”
I find it difficult to believe that it happens in an ashkenazic shul. He should follow the derech of this “sephardic mashgiach of a charedi yeshiva” and try to be close to his mechallel shabbos cousin, so he could try and influence him to once again keep shabbos. by simply cutting ties with him, he is basicly saying, get lost, go be mechallel shabbos I dont care. this mashgiach has it right.
