These attacks serve two functions, both of which Omar has named clearly: They intend to shut down conversation about American foreign policy and the Israeli government’s treatment of Palestinians, and to strip her of her personhood and credibility as a lawmaker. Omar has rightly refused to accept these as the terms under which she must speak. Earlier this week, she tweeted: “We must be willing to combat hate of all kinds while also calling out oppression of all kinds. I will do my best to live up to that. I hope my colleagues will join me in doing the same.” Whether they will or not remains an open question.
