No open discussion is possible

I’ve felt a hardening of attitudes within my own progressive community. People who are open to discussion on other issues of politics and society have closed off when it comes to Israel/Gaza — no open discussion is possible.
I experience this in my non-Jewish friends, but it worries me that the spirit of argument and disagreement within our own lot is not of this moment. I disagree with vocal groups who pretend to speak for us all (as if anyone could) but would like some real open talk among ourselves.
