a”...the agent asked Martinek “to have all Coalition Board members sign a statement that the Coalition will not ‘picket’ or ‘protest’ outside Planned Parenthood...”
So have them sign it, get the tax exempt status then have them all resign and get new board members.
Or...since the members of the organization don't give up their personal right to have political positions, and since this particular organization is related to this issue, it would hardly be surprising if all its members showed up to protest at the same place, in their capacity as individual citizens. No involvement by the organization required.
