poetry and human rights

tomorrow i am on a panel on poetry and human rights, at the university of maine in augusta. the panel coordinator today asked me for a list of a half dozen poets whose work has influenced me in this area of thinking, so here is a list, the first six who came to mind:
Nazim Hikmet
Fadhil al-Azzawi
Carolyn Forche
Czeslaw Milosz
Paul Celan
Nicolas Guillen

Who would you add?
