One lone person taking potshots is "terrorism"?
he is originally from North Carolina where the terrorist "Army of God" has been highly active:
Robert Lewis Dear is one of many religious extremists bred in North Carolina: Domestic terrorists threaten us more than Syrian refugees.
North Carolina? It sounds absurd. When we think about immigration and terrorism, we think of Syria. But that’s not where our casualties are coming from. On Friday, a gunman killed three people and wounded nine more at a Planned Parenthood clinic in Colorado. The suspect is white American Robert Lewis Dear. When police apprehended Dear, he uttered one telltale phrase: “no more baby parts.” People who have known or met Dear say he wasn’t a regular churchgoer. But they also report that he believed devoutly in the Bible and that he claimed to have read it “cover to cover.” In an online forum, Dear apparently spoke of Jesus and the “end times.” He painted or posted crosses on at least three of his homes.
Dear moved to Colorado last year from North Carolina, where he had been living. For two decades, the Tar Heel State has been a hotbed of religious extremism, fueled by clerics who preach holy war. The result is a stream of interstate terrorism.
It began with Eric Rudolph, a Holocaust denier who grew up in the Christian Identity movement. In 1996, Rudolph traveled from North Carolina to Atlanta, where he detonated a bomb at the Olympics, killing one person and injuring more than 100 others. A year later, Rudolph bombed a lesbian bar in Atlanta, wounding five people. In 1998, he bombed a reproductive health clinic in Birmingham, Alabama, killing a security guard and injuring a nurse. The “Army of God,” which hosts Rudolph’s writings, claimed credit for his attacks.

Some radio discussion suggests he had actual ties with the terrorist Army of God but I have not seen any authentication of this as of yet. If it is true that he was associated with them, had known sympathies, or is in league with them in any way, then the term "terrorist" is apropos.
