His manifesto also included memes and copy pasta.He listened to meme music as he drove to the mosque, he said "Subscribe to Pewdiepie" before he shot the first victim.
The fact that he was a member of an online community that considered his views normal is extremely significant.
Oh yeah? How about the fact that he drove a car, or ate meat or spoke english or traveled a lot?
The "online radicalization" thing is complete and total bullshit: it's an excuse to ramp up the totalitarian surveillance state in a more obvious way than the "war on terror" -now it's a war on people who read things on the internet. Magic internet forums might make me into a terrorist ... or a hacker; better put me in prison!
And you don’t think his manifesto is propaganda rather than a attempt at reliable narration?
Coming to “the truth” seeing the reality of the world at first hand is a much more stirring story than being radicalised by lies on the Internet. Plus it fits directly into all the other racist propaganda put out by white supremacists about the state of Europe and France in particular.
