As always, a little history is in order.
It may be apparent that there is another of those gawd-awful "national conversations" going on about the recent (re-)emergence of Antifa, the active anti-fascists who aren't afraid of mixing thing up and physically fighting the rightists, fascists and neo-Nazis in street brawls that have gotten a bit of attention among the "news" media.
Horst Wessel was a Nazi who wrote the lyrics to a song that became the anthem of the Nazi Party in 1930 and of Nazi Germany from 1933 to 1945. Some say he wrote the music, too, but it's too close to the well-known hymn "How Great Thou Art" for that to be true.
Host Wessel became a Nazi martyr after his murder by a Communist in Berlin in 1930. Joseph Goebbels masterfully parlayed his death to enhance the Nazi Party and denigrate the Communists. They were, after all, arch enemies throughout the interwar and WWII periods.
For some reason, they're arch-enemies again. "Antifa" you see, are today's "Communists." The "Alt-Right" however you want to define it, are today's Nazis (some are literal Nazis, most are cosplayers).
Street brawls between Nazis and their opponents were a feature of the Late Weimar Republic in Germany. The authorities tended not to intervene (not unlike Charlottesville) and let the boys have at one another as they chose. Horst Wessel was one of the brawlers, but he was killed over a personal money matter between him, his girlfriend, and their landlady. Or so it would seem. The truth of the matter is subject to scholarly dispute to this day. Overlay the politics of the day (then and now) and there's no there's no telling what really happened.
It appears that the rightist media in this country is attempting to turn a fellow named Keith Campbell into a Martyr for the Cause (Horst Wessel?) because he was seen being beat up on camera in Berkeley. Antifa did the deed. Video clips I've seen show him running away from several black-clad dudes who catch up to him and start wailing away as he curls up to protect himself. A black man runs to his rescue and stops the beating while a crowd gathers, some threatening, others attempting to stop the violence. Eventually, the crowd disperses and Campbell is led away, shaken but ambulatory.
According to the reports I've seen, Campbell is a well-known white rightist provocateur who sees his mission as "defeating the left" by any means necessary. Yes well, that always turns out well, right?
As a provocateur, of course, he's more than a little interested in provoking his leftist/Communist/Antifa enemies into a fight, and so when it happened on camera in Berkeley, he gained cred and cachet both with the rightist and mainstream media as a poor little white boy being mercilessly beaten by "Antifa thugs."
Thus a narrative was established about the "violent left," versus the "peaceful right."
Of course it's not true, but that's another issue altogether.
As a sidenote, the use of "peaceful" as opposed to "nonviolent" to describe marches and demonstrations is very grating to me. Peaceful implies passive, whereas nonviolent can mean a lot of not very peaceful things at all. But somehow, during the last few years, demonstrations and marches have been categorized as "peaceful" or "violent" depending on whether somebody breaks a window, starts a dumpster fire, wears black or the police use chemical weapons against the demonstrators. It's bizarre. Another issue is the problem of categorizing protesters, counter-protesters, and civilian observers. And then there are all the infiltrators...
Now that there are brawlers on all sides, it's all a muddle, no?
Anyway, one of the chief efforts of the Overclass during the current time of troubles has been to keep the Left (so-called) "peaceful" by any means necessary -- primarily by invoking Saints Ghandi (sic) and MLK incessantly and often inappropriately.
The fear of an active and muscular left (real or so-called) that fights back is palpable among Our Betters. There is no such fear of a violent right.
In fact, there's tacit and sometimes overt encouragement of it.
The more violence from the right including the Nazis, the better.
Heather Heyer was killed and dozens of "peaceful" demonstrators in Charlottesville were injured by white rightists rallying and going berzerk a few weeks ago. The white right and their allies have killed dozens of people and injured hundreds in the last few years, but it is always, always, always important to keep the Left (what there is of it) "peaceful," passive, and pathetic in the face of the violence both from the white right and the state. Don't forget what happened at Standing Rock and during so many other demonstrations for justice.
And then there's the whole frustrating and largely bogus "free speech" argument that I won't get into for now.
The point, ultimately, is that despite the disgust most Americans have for the white rightists, keeping them on an even or higher plane than the feared Left, and letting them be as unpeaceful as they want to be, while the Left (such as it is) does nothing or less is the received narrative.
So far, Antifa refuses to play.
