Terrorism is defined as inciting terror, however it has more recently come to be defined as "the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political aims." (one of three Dictionary.com definitions vs. the Oxford Dictionary definition)
This is sort of U.S. specific, but based on how you view/define terrorism, would you count last week's school shooting in Florida as an act of terrorism? It was the eighteenth school shooting in the United States this year and I've seen a lot of articles and social media posts debating whether or not it should be considered terrorism (and if whether or not that distinction is based on the race of the perpetrator, especially when covered by major media outlets). I personally am still debating this with myself and am not sure, but it's an interesting thought-- what do you guys think?
