The main characteristic of a Domestic Terrorist is being primarily inspired by US-based extremist ideologies. Domestic terrorism involves individuals or groups that commit violent acts within their own country, specifically motivated by domestic political, social, or ideological grievances. This motivation tends to stem from a desire to influence or disrupt governmental processes, societal norms, or to instill fear within the general population.
In contrast, being connected to foreign extremist movements would categorize an individual as engaging in international terrorism rather than domestic. Focus on economic advancement does not align with the fundamental principles of terrorism, which typically involve coercion or intimidation through violence. Promoting peaceable protests is contrary to the definition of terrorism, as it emphasizes non-violent action rather than acts intended to cause harm or instigate fear. Thus, the focus on U.S.-based extremist ideologies is a distinctive feature that characterizes domestic terrorism.
