“I am not sure that a place that would consider hiring a YCT graduate really cares what the Novominsker Rebbe says (one of the signers) or for that matter even knows who the Novominsker Rebbe is”
Are you inferring that thos who might be on a rabbinic search committee are unaware of any number of the gedolim? And would not care who they are? Even the horrible radically anti religious, anti Israel publication that Avi Weiss and his band of fools write to, The Forward, acknowledged a number of the members as important Rabbis. Much to its own chagrin. You are being Motzei Shem ra on those Shuls, or they too have left Orthodoxy.
