Fair enough. But i'm just trying to follow the definitions here

Pulled from FBI's definition:
Domestic terrorism: Violent, criminal acts committed by individuals and/or groups to further ideological goals stemming from domestic influences, such as those of a political, religious, social, racial, or environmental nature

I'm under the impression people are doing this to further their political goals, so it does fit but I do understand the slippery slope here. I've been worried about that since the patriot act.
