This stuff is complicated and tedious to figure out. Plenty of rhetoric at both ends of the spectrum. Neither side (far right/far left) really have the resources to do more than what they are doing now - taking advantage of unrest and squeezing into the margins and making things worse, at certain moments in time
The federal government has zero appetite for going after these groups (Boogaloo Bois, Antifa, Proud Boys, blah, blah, blah). In reality there aren't enough of them that are full time. Besides, plenty of evidence on both sides that members of local and federal law enforcement align with the ideologies on both sides of the fence and are part time members. This hampers efforts to affect these groups long term. For the most part, members of these groups are part time, hanging out in the woods on the weekend, trying to improve their poor marksmanship.
I don't subscribe to the idea that American Society will be fractured and that fracture will be initiated by these groups. They really aren't that sophisticated to operate at that level. With that said, the far right groups are the more dangerous in terms of a single, mass casualty incident. Proof is in the pudding - OKC bombing, Eric Rudolph, and other, smaller incidents. They have better training and their core, permanent groups are dedicated to their cause.
While the assault on the Capitol building was terrible, it was a target of opportunity. Frankly, I'm sure there are many on the far right who are kicking themselves in the ass as they saw the lack of security demonstrated. If this had been truly a planned, coordinated event by a sophisticated group, the body count would have been higher, there would have been big booms. These groups would never go head to head with federal law enforcement unless they have to. What we saw on tv was a bunch of idiots vandalizing our capitol. There were pipe bombs found but not much has been said about their level of sophistication. That could be an entirely different event with a different purpose.
But, we can sit on these forums and spew partisan rhetoric. It really means nothing. It will be interesting to see how the end of the month plays out. Federal law enforcement is doing what it normally does, react. They will dedicate their full array of assets for a short time against these groups and make it very difficult for them to operate. Come 1 FEB or so, it will go back to business as usual.
