You know, it's interesting... Today, there was an article about the psychotic leader of a religious commune who was responsible for multiple bombings at specific oil-related targets, and not once was the word "terrorist" mentioned in the entire article (http://www.thestar.com/news/canada/article/748616--pipeline-bomber-released-by-rcmp?bn=1).
Surprising to me, given that when an article has even a whisper of the word "terrorist", it's definitely Headline News.
I would think that regardless of the reasons behind "terrorist" actions, a terrorist act is exactly that, a terrorist act.
I guess it depends on who you ask..
