plus all the violence committed by Nazis (e.g. the Heather Heyer murder and the other actions counted as right-wing domestic terrorism)
"all of the violence", you listed one death. One death is a tragedy, but it's not a massively systematic problem unless we act like it is and turn it into one. You also act like there isn't such a thing as left-wing domestic terrorism. That terrorism killed more people in a single event, 7/7/16, than that nutjob running someone over did. What about the mob of nazis and anti-facists getting into fights in Berkeley? If you're not committed to one of those groups, it's just as bad. It's mob violence either way.
Nazis suck, but please try to be objective. When you frame the argument as you are, you are setting up flamebait. Some nazi will use your exaggerations against you.
