For those of you who haven't seen the notices, there will be a demonstration on Sunday at 6:30pm in Kikar Zion in Jerusalem.
This is for those of us who are clinging by our fingernails to the belief that peaceful demonstrations have some effect.
And that there are reasonable people in Israel, who despite their disagreements with us, think that Olmert's decision to disregard the compromise worked out that would have avoided the violence in Amona was proof of an appalling lack of judgement.
And that there is still hope that we can convince our teenagers that they are not backed into a corner yet - and that there are other ways to help their fellow Jews than mixing it up with policemen on horses.
And, if nothing else, G-d will take notice of our cries.
