If you want to understand why this guy did what he did, and you want to try to figure out whether it's terrorism or not, you need to read up on who he was and what he believed. https://www.theglobeandmail.com/canada/article-facebook-post-connected-to-suspect-in-van-rampage-cites-incel/ Minassian appears to have been an "Incel" or "Involuntary celibate". If you have no idea what 4chan is, or what an Incel is, or why it's relevant to things like ISIS, white supremacy, toxic masculinity, etc., then you have a lot of reading to do. So much of what has been happening with respect to terrorism, white supremacist radicalism, etc, not just here in the US but globally, over the last 20 years, is related to the rise of the internet and all of these sub-cultures where men (young men especially) are preyed upon because they are vulnerable to overtures about how they are victims and deserve [insert whatever here. 42 virgins, a prom date, a job that a black person has, etc]. So while I'm not sure I can get all the way to calling this guy a terrorist, it would appear that the driving force behind his actions is not unlike the driving force behind pretty much all this . Dudes are f*cked up.
