A very basic Google search destroys that right-wing propaganda. It is in fact the right who are responsible for the vast majority of violence: https://www.businessinsider.com/right-wing-extremists-kill-329-since-1994-antifa-killed-none-2020-7
The violence most often shown on right-wing media as “leftist riots” are usually actually police violence aimed at protestors or right-wingers either attacking protestors or committing vandalism in an attempt to incite violence and frame the protestors.
I will concede that since this article was published, one man who identified as an anti-fascist, Michael Reinoehl, killed someone in what he said was self-defense. We’ll never know if that was true, since the police shot him dead before he ever got his day in court.
Regardless, even the FBI and DHS have stated that the threat of violence from right-wing groups is THE major threat to national security right now. https://www.politico.com/news/2020/09/04/white-supremacists-terror-threat-dhs-409236
