It is a 22 minute video, but it is one that we really need to see. He mentions Anders Breivik and his descent into violence. Breivik said that the purpose of violence was to break through the wall the media has placed around the topic of Islam. What drove him to mass murder? The same kinds of things that drove Darren Osborne?
There is good reason to expect many Muslims to leave Islam given the knowledge we now have and the access we have to Muslims.
This is an excellent talk, highly recommended.
