I think that might be jumping the gun? That's a very popular meme but I'm not sure it's at all accurate -- I haven't heard a convincing case. Perhaps you could explain your thinking here? Here's my take: The FBI calls people involved with the earth liberation front "ecoterrorists". I don't think most people in the ELF would deny that their efforts are motivated by environmentalism, or oppose the "eco" label being applied to those efforts. The "extremists" described here would probably not say that they were motivated by "white nationalism" or a desire to ethnic cleanse non-white people. No doubt there are some of those out there, but certainly you couldn't describe the pizza gate attacker in that way, nor would they self-describe that way. I think the vague "extremist" label might be about as good as you could do, seeing as how unrelated some of these things are. You might be able to call it "right-wing extremism" but then you're making things partisan, and it's understandable that the FBI wouldn't want to do that.
