It's not, that link mentioned how the trend changed in the 90s and now we have the latest figures.
So the FBI link your posted strongly supports my assertion that "74 percent of those killings were committed by right wing extremists. Only 2 percent of those deaths were at the hands of left wing extremists." is incorrect from commentary provided by the FBI in their testimony before the Senate Select Committee on Intelligence in Washington, DC on February 06, 2002.
From the FBI testimony - "The second category of domestic terrorists, left-wing groups, generally profess a revolutionary socialist doctrine and view themselves as protectors of the people against the “dehumanizing effects” of capitalism and imperialism. They aim to bring about change in the United States and believe that this change can be realized through revolution rather than through the established political process. From the 1960s to the 1980s, leftist-oriented extremist groups posed the most serious domestic terrorist threat to the United States. In the 1980s, however, the fortunes of the leftist movement changed dramatically as law enforcement dismantled the infrastructure of many of these groups, and the fall of communism in Eastern Europe deprived the movement of its ideological foundation and patronage."
With leftists, they talk of monetary damages (like animal rights groups), not human casualties.
According to a major report published by the Government Accountability Office in April 2017, there were 62 fatal “far-right violent extremist-motivated attacks” leading to 106 deaths between 12 September 2001 and 31 December 2016. The most lethal of these, according to the report, was white supremacist Dylann Roof’s June 2015 shooting massacre at the American Emanuel AME Church in Charleston, South Carolina, which killed nine people.
According to START (the University of Maryland’s National Consortium for the Study of Terrorism and Responses to Terrorism), there were 81 fatal far-right extremist attacks in the U.S. between 12 September 2001 and 31 December 2014, leading to 131 deaths.

So this merely demonstrates that the figures you provided are incorrect (as stated by the FBI), and the figures you provided directly above.
I don't disagree that right-wing domestic extremists have caused more deaths in the U.S. than left-wing domestic extremists in the last decade or two. We need law enforcement to focus more on eliminating domestic terrorism.
They are not incorrect, different organizations are using their own methodologies to arrive at the figures

I will go with the official figures that federal law enforcement is providing rather than believe un-researched figures from third party organizations that have political agendas.
You can go with whatever agenda that suits you
Clearly you follow whatever agenda suits you -- even when facts do not support the assertions.
Yes, I have an agenda of numbers and facts
