What happened at Columbine was the logical conclusion to the upholding of an American ethos that affirms a privilege to arms and violence as a valid response to grievance, which is itself rooted in our history of (race-based) slavery. More directly, the Columbine shooters were influenced by Timothy McVeigh and the militia movement, who was and which were explicitly white supremacist.

What's disgusting is that this keeps happening, and that white Americans are so married to this ethos that they'll sacrifice their children to maintain it, and that people like you would rather flag and dismiss a post pointing out this dynamic than introspect. What's inflammatory is this purposeful and obstinate denial, while all the world watches in pity.
