Every single day in this country someone dies directly because of the political decrees of the ruling class. Political violence is an every day occurance, its just normalized.
Charlie Kirk didn't die because he was exercising "free speech." He was a war profiteer in the class war. He profited of the rise of open fascism as a paid agent of a billionaire.
This being America I doubt the shooter had a coherent political view. But this is ulitmately a result of deteriorating conditions, that Kirk profited off helping create.
