“true clowns like Avi Weiss”
First, he is Rabbi Avi Weiss.
No less a figure than Rabbi Druckman himself has been quoted as complaining that the charedi world doesn’t refer to DL rabbis by the appropriate title. One can disagree with him, but don’t disrespect him.
Second, Rabbi Avi Weiss is someone who has personally brought many Jews to mitzvah observance, and who has constantly spoken out against anti-Semites and others who oppress us, all over the world. Few if any of us can stand in his shoes. If that makes him a clown, may we have many more such clowns.
