They are not even remotely equal.
No, they tend to do different things. The right-wing militias plot (unsuccessfully) to kidnap governors while left-wing extremists rage in the streets, loot and vandalize businesses and set things on fire since 2014 when they did it in Ferguson.
Now in Philadelphia and DC.
30 officers hurt amid looting, arson after police kill Black man in Philadelphia
This is political violence and should not be ignored or downplayed because of political correctness!
For months in Portland leftists' have been rioting without much respite. In Seattle they even occupied territory.
All that is affecting the economies and the quality of life in major US cities and thus has a lot more effect on people's lives than some idiotic failed plot to kidnap the governor.
Regardless of who says what, it's overwhelmingly the army of right wing authoritarian morons who respond with violence and threats of violence.
"Army" is quite an exaggeration. There are right wing militias, but there are also left-wing ones. Like the black-only militia we have here in Atlanta.
The number of people who oppose trump and make threats of violence are negligible in comparison.
That is not the ONLY gauge for political violence.
But if you want, what about
this guy:
They're hardly even worth mentioning in terms of actual threat and actual violence being threatened and committed in the US right now.
Except that they revel in wanton destruction in many US cities: Ferguson, Baltimore, Minneapolis, Milwaukee, Kenosha, New York City, Philadelphia, DC, Atlanta, Portland, Seattle, Charlotte and many others.
