The Alt-Right proclaimed itself as such, under Richard Spencer, anyway, and that created confusion when Bannon also used the term, and I don't believe he did so in reference to Spencer's group, specifically, but we've already seen that fragile delineation dissolved. The attempt to brand counter-protesters as the "Alt-Left" is ironic in that, by its very virtue, it implies an astonishing critique of the Alt-Right (and Bannon/Breitbart); because clearly it is designating "Alt-Left" as a pejorative.
By attempting to slander #antifa you guys are surrendering
absolute moral authority. This is what happens when you let people who don't know how to drive steer the bus. This is why I was and remain a #NeverTrumper.
