They are certainly part of something - the fabric of American history. There is a complex explanation to how and why these splinter groups from the 'independent frontiersman' tradition went off of in the fascist direction (don't discount the role-playing, dressing-up theatrical aspect of this), but that's by the way. Their central issue is refusal to share power with less privileged groups -- and it's illusory, because they never were anything more than disposable tools of the real privileged class.
The dissent and dissatisfaction with the current political system may yet prove to be more far-reaching.
Yes, of course, but that legitimate dissatisfaction does not reside in, and is not expressed by, these gangs. There are far more numerous groups of citizens who can - and have - put forth a
much more convincing case for having been robbed of their rights and votes and consideration and share of the nation's benefits.
There is plenty wrong with the system - but that's not what the Trumpites are protesting about. Most of them probably couldn't articulate what, exactly, they think has been taken from them. They're enraged, because they've been worked up to the rage they so enjoy, and they're unwilling to let the conductor of their collective tantrum go. Who else will give them the world stage to perform on? Who else will make them feel so 'special' and 'loved'?
These 'mobs' have been around in different guises since the end of the Civil War
Since the dawn of civilization!
and the question of their remaining existence needs to be explored and not downplayed.
Explored, I think it has been. Solved is another problem. But nothing good will be accomplished either by giving them more publicity or by appeasing them. They're a by-product of the interacting forces in the society: their faces, chants, uniforms and hairstyles change; their weapons a periodically upgraded from rocks to pitchfork to assault rifle, but they are always potentially present, ready to spring up from the cracks in any nation's integrity, at any time.
Trump played to these mobs because like many others he knew of them.
The vein was rich and accessible. The tool was in his hand.

I find it hard to believe that people who show so much disdain would go home, sit quietly at the dinner table, smile, and ask 'darling, what's for dinner?'
More likely, "Hoy, Babe, we goddany beer?" But, yes, of course they won't go peacefully. This was a dress rehearsal for the 20th. They need a few minutes' time out under a riot cop's knee... They need to be humiliated and left leaderless for a while. They'll split off into their local, specialized gangs, drift off into oblivion for a while, and bide their time. They should be kept under close scrutiny. Unfortunately, they have far too many sympathizers in the various police forces. Even more unfortunately, the problems of the disenfranchised and legitimately angry minorities, and the underpaid, underappreciated, underserviced, long-suffering majority will be demonstrated in more public displays, which will give this rabble more excuses to stage violent clashes. They've got the taste for it now, the habit of organizing, and the tacit approval of quite a large number of Murdoch-indoctrinated citizens and the toxic right-wing media to furnish their alternate reality.
