Material conditions are still too good in the US for the type of extremism you write about to manifest (yet). People who are getting fucked over but not starving won't be murdering anyone anytime soon.
However, the trend is clear, your observation is correct about where capitalists would like to take things. This will worsen conditions and push more and more people towards extremism... which is where it is up to "us" to push people leftward and point their anger where it belongs, towards capitalists/capitalism.
As I find myself repeating a lot, things just simply aren't bad enough yet across the board in the US to see the unrest which is required for actual change. It's going to get worse, worse probably than any of us can imagine right now, before it starts to get any better. If you can see the inevitable future coming then you can see things like this court case being another domino in a line of them that is still fuzzy. It won't change anything on its own, but all these small events will eventually add up to something big. We just aren't there yet, and that's probably good in some ways because there is effectively no leftist movement of any sort in the US. Like the fact that these cases get decided in the obviously far right way, and that we expect it, shows that the left is totally annihilated in the US. Absolutely no power currently. Just gotta work on changing that however we can. It's very bleak.
