Counterpoint to what? You claimed one political side does the shootings, I just verified if you are aware which side. If you have shown hundreds of right wing political activists shooting the Democrat politicians then your request might have made some sense. Other than OK bombing I've not heard of right wing political terror, all famous terrorists are leftists.
PS. Well, remembered another one, Ted "UNA Bomber" Kaczynski. That's two (if we count McVeigh right wing from being religious and pro-gun) against entire organizations and individuals on the left. From Angela Davis to the dude caught couple of weeks ago while trying to assassinate a Justice, from the M19CO to the Weather Underground.
A 2017 report by The Nation Institute and the Center for Investigative Reporting analyzed a list of the terrorist incidents which occurred in the US between 2008 and 2016.[0] It found:[1] 115 Far right inspired terrorist incidents. 35% of these incidents were foiled (this number means that no terrorist attacks occurred) and 29% of them resulted in fatalities. These incidents caused 79 deaths.
(...) 19 Far left inspired terrorist incidents. 20% of these terrorist incidents were foiled (this number means that no terrorist attacks occurred) and 10% of them resulted in fatalities. Two of these incidents were described as "plausibly" attributed to a perpetrator with left-wing sympathies and caused 7 deaths. These are not included in the official government database.[2]

I am sorry, even Wikipedia does not put at least half of these as right-wing radicals. "Charlottesville Attack" you mean which one, there had been a lot of violence between left and right thugs, do you mean the guy who got spooked and drove a car through a crowd blocking the roadway? And US Capitol Riot, really? Violent Parading? That's right wing violence? JFYI, leftists "paraded" there countless times, most notably during Kavanaugh confirmation. And they actually bombed Senate in 1983.
