PDP didn't commit any violence. He contributes to the rhetoric and the perpetuation of the culture that produces violent offenders. By pretending things like Nazism are laughing matters he breeds people who buy into the rhetoric, spread it, reinforce it and galvanize those who commit this kind of violence. By not admonishing the people in those groups who see him as a fucking hero, he continues a trend that already exists of people seeing that it's OK to stick to your beliefs about the inferiority of "undesirable" people. PDP had a simple job: Make sure that people watching his videos understand that white supremacy is wrong, bigotry is sick and equality is something that should be sought by everyone. Something that should be simple if you actually understand the stakes of what is going on, have empathy and are actually invested in bettering the world but he chose to double down time and time again. There is no single through line from PDP to this mass shooter but PDP contributes to the pitcher of water that makes up the kool-aid that people just like these maniacs drink from. Just like Alex Jones & Beitbart & Milo Y. & Richard Spencer, and on.
