“For instance, they do chessed extremely well. “
I am not sure if much what they do is actually chessed.
In addition, any Rov who I have known is constantly involved in chesed of all types.
There is a reason why people are constantly speaking to them, it is not only matters of Halacha.
I would say even Avi Weiss, who is a problem, still does more chessd than reform rabbis, although it is tempered by the michsholim he causes.
(Some of his activist talmidim, on the other hand, do no chessed at all, they actively seek to harm frum yidden and communities)
