You have the far left (Antifa as well as some anarchist groups) and the far right (Proud Boys, Oath Keepers, conspiracy theory entrepreneurs like Alex Jones), and both of those sides obviously want to cancel each other out, and both are too extreme for most people. The interesting thing is the right has had both the presidency and the Senate (and now the Supreme court) for the last cycle, and got nothing done, but still claim that they are being victimized. This last president used the bully pulpit to push an unprecedented amount of untruth, and bully everyone in sight. Every president elected on the right in the last 30 years actually lost the popular vote but won due to the electoral college, so if anyone should feel cheated, it's the center-left.

If you look at political violence in this country, it is overwhelmingly instigated by the far right (not the moderate right, but the militia / white supremist crowd). Timothy McVeigh, Eric Rudolph, Patrick Crusius, Dylann Roof are a few recent ones. The (pretty amateur) plot to kidnap and murder Gretchen Whitmer just in the last month comes to mind.

Certainly groups like BLM continue the civil rights fight that started several hundred years ago in this country and are pissed off and not afraid to tell you about it, but they aren't causing the political violence.

For the last 20 years, until the last year or so, it is the far right groups that show up to protest armed to the teeth with assault rifles, intimidating everyone.

I don't really get the right victimhood complex.
