How about publishing a full list of Rabbonim, Roshei Yeshiva, and Askonim who will be organizing and/or participating–in advance of this protest. That will allow us to make informed decisions as to which institutions and causes we would be inclined to continue to support. The, after the event, publish a list of those who actually attended to also help make these determinations.
It would be great if one or two organizations would schedule a counterprotest outside of Barclay’s against this Chillul Hashem.
