Rabbis Who Asked That We Atone for Our Sinful Acts Against Palestinians

I just read this in a e-mail I received:

"Rabbis across the United States will extol the virtues and high moral principles of Judaism, yet each one (among those working for a congregation that owns a building) will ignore our guilt in the destruction of Palestinian society."

I have written frequently about the core values of Judaism such as "Justice, justice, shall you pursue", “You shall not wrong a stranger or oppress him, for you were strangers in the land of Egypt”, etc.

How could rabbis during Yom Kippur when we, as Jewish people, atone for our sins not speak out about the violations of these teachings of Judaism by the Government of Israel in its treatment of the Palestinians?

Is the writer of this message correct?

I would appreciate if you would, in a comment, let me know the name of a rabbi who did indeed, in a sermon, ask that the members of the congregation, as a Jewish community, atone for the violations by the Government of Israel of the human and civil rights of Palestinians.
