Borer has been a member of various organizations and campaigns which advocate peace with justice in the
Middle East, and which protest the Israeli occupation and Israeli violations of human rights. She has lectured extensively and has written on the Israeli-Palestinian conflict, and on Palestinian solidarity activism. Borer was a passenger on the vessel
Audacity of Hope, a member of the 2011
Freedom Flotilla II which, sailing from
Greece, attempted to break the Israeli
Blockade of the Gaza Strip. Fellow passengers included
Hedy Epstein and
Alice Walker. Before the voyage, the
Los Angeles Times carried an op-ed by Borer in which she explained her motivation and wrote that "a society built on conquest and dispossession would have to dehumanize the conquered in order to continue to dispossess and oppress them" and "We wish to say to the Palestinians that, yes, there are people in Israel who know that any viable future for the Middle East must be based on a just peace – not the forced imposition spelled out by Netanyahu to Congress – or else we are all doomed." In October 2012, Borer travelled with
Noam Chomsky and a group of other colleagues to
Gaza in order to attend a linguistics conference at the
Islamic University of Gaza. Following that trip, they all co-signed a statement entitled
Nous accusons... on how the mainstream media allegedly fails to report on Israeli atrocities against civilians in
Gaza, also published in French. ==Selected publications==
