You haven't seen it because you don't look. I have no liking for Antifa, and I have condemned the harrassment campaign targeting Huckabee and others as well as Maxine Water's statements encouraging harassment.
When are you going to condemn your side's violence or will you just blame that too on the left?
Okay, I am still quibbling with this line of argument of yours, mostly because I think it fails to make at least one important distinction, maybe two.
No one on the left, of any import whatsoever, is egging on Antifa, openly or veiled. No one expresses sympathy for their tactics. No one I have seen, who would speak with some authority on Antifa's ideological affiliation, would want anything to do with Democrats or liberals.
On the other side, we have the likes of Steve Bannon, Miller, and the Trumpy, engaging in rhetoric that closely resembles rhetoric on the far right, the alt-right, and White supremacists, and we have outright Nazis, KKK (Duke) endorsing the Trumpy. So, there's an easily detectable affiliation and ideological proximity.
Moreover, Maxine Waters called upon folks, in the name of decency and humanity, to confront cabinet members over the gratuitous brutality inflicted on the children of refugees. She abstained from, and rejected, calls to violence. Most importantly, she abstained from depicting the cabinet members she thought needed confronting in apocalyptic, dehumanizing, demonizing terms designed to lessen the inhibitions against violence against them. Her call for confrontation isn't problematic because they were designed to cause violence, but because in the heated atmosphere things could get out of hand. The distinction isn't easy to see, but it is salient, particularly compared to the Trumpy's apocalyptic, demonizing rhetoric, and open praise for violence ("enemies of the people", "rapists", "body-slam" etc. etc. etc.).
Finally, I think you should take the article quoted in your OP more seriously. There is, as you won't tire to point out, violence on both sides, even though deadly violence originates mostly on the right. That is dangerous, and needs to be condemned. The real danger is, however, the use of that violence, and the warnings against it, to undermine democratic procedures and the rule of law, and I see none of that on the left.
