I think it's lazy to say social media is to blame. Political murder and radical ideas have been around pretty much from the beginning of history. Is social media really more effective in radicalizing people than folklore, religion or mass propaganda? People didn't change much, only the means by which they communicate and share ideas.
I think its not so much the specific social media platforms, its the fundamental increase in how densely connected the social graph is and how much information flows across it. We don’t have the capacity to process it as individuals and our instincts lead us astray.
