On the other hand, the real movements for peace, such as the gatherings in Union Square of families and friends of the victims, which welcome a mix of solidarity, patriotism and those asking for peace as the memorial to their dead, rather than hate and murder, are far more likely to bridge the gaps of anger in peoples hearts.
That the "Left-wing" measures its success by how many people it alienates is a large reason why it has been so ineffectual. You should be measuring your success by how many people of a wide range of views you bring together in coalition.
