I take the OP's original point to be that far-right ideological extremists have targeted, injured, and killed orders of magnitude more people than far-left ideological extremists during the last few years, which seems to me to be incontrovertible without resort to sophistry. Also, given that the larger context of this discussion is terrorist attacks rather than political confrontations that turned violent, it's relevant to ask "how many random bystanders have been killed when self-identified white supremacists opened fire on crowds vs. bystanders killed when self-identified 'antifa' have done so."
