Some would say that the assasinations of JFK, MLK, RFK were examples of domestic terrorism.
The Hinckley shooting of Reagan was carried out by a single, chemically-deranged gunman (fueled by Valium) whose parents were long time friends of Reagan's vice president - George HW Bush (so I don't count that as terrorism - just another example of the Secret Service selectively allowing themselves to be used & misdirected. Hinckley should have never come within 300 yards of Reagan that day).
Some say that the Janet Reno directed destruction of the Waco compound of David Koresh was state sponsored terrorism, just as was the Ruby Ridge fiasco.
The Unabomber was another single, long running act of terrorism which stretched across a decade - definitely domestic in nature (and not state sponsored).
There is little doubt that the Oklahoma City bombing of 1995 was an act of domestic terrorism, although questions linger still as to which individuals escaped capture, while others insist it was pulled off by a pair of miscreants.
Millions of people feel that 9/11/2001 was also terrorism (but many are divided whether there was a domestic flavor sprinkled amongst the chaos of that Tuesday - as well as a foreign planned and executed day of terror) - while the first attack on the WTC in 1993 was not domestic in nature. (Building WTC7 which housed the records of various US agencies like the FBI, ATF, IRS and CIA, magically disintegrated several hours after the last twin tower collapsed).
January 6, 2021 was simply the latest act of domestic terrorism which captivated the attentions of millions of Americans who were going about their activities that afternoon - when the speakers/Trump surrogates - at the elipse urged thousands of MAGA to march to the capitol and FIGHT (trial by combat - Rudy Guiliani). There is zero doubt as to who instigated and caused the attempted coup de'tat that day, and it wasn't BLM, Antifa or any liberal flavored organizations.

The IssueThere has been a significant rise in the number of domestic terrorist attacks and plots at demonstrations in the United States, according to new CSIS data. The result is escalating violence in U.S. cities between extremists from opposing sides, a major break from historical trends. In 2021, over half of all domestic terrorist incidents occurred in the context of metropolitan demonstrations. In addition, the most frequent targets of attacks were government, military, and law enforcement agencies, who are increasingly at the center of domestic terrorism by extremists of all ideologies.
