The senseless killing of British MP Jo Cox is "a manifestation of a coarseness in our politics and hatred toward the other that we must not tolerate." That from American politician Gabby Giffords, herself the target of an assassination attempt. We must do better. We must hold each other to account. We must condemn threats against women in politics, because the death of Jo Cox shows what can happen when threats are actualized. We must not let threatening, misogynistic, or hateful discourse online or elsewhere go unopposed. We must not let hate win and we must not let people try to tell us that we cannot be better.
