“Why can’t they”?

From the Angry Arab
I hate it when I hear American liberals say: why can't the Palestinians resort to peaceful resistance? Answer: 1) why is the Palestinian national movement the only movement that is asked to resort to non-violence? American liberals supported the struggle for blacks against apartheid without requesting or insisting that their struggle strictly adhere to non-violence. 2) the Palestinians largely stuck to peaceful struggle from 1948 to mid-1960s: and Israeli occupation troops killed thousands of Palestinian civilians who tried to peacefully enter Israel to check on their properties and houses (read the tally in Benny Morris' Righteous Victims). 3) some Palestinians still resort to non-violence, and Israel still manages to shoot at them: "Naalin: Protestors say IDF using live fire."
