He talks about people like Richard Dawkins. Some call him bigoted or a racist because he has been critical of Islam. But the exMuslms or closet Muslims in Muslim lands that Rizvi talks to tend to like him. They relate to his anger and verbal and written attack on religion. And they are often unable to speak out themselves.
He talks about if you want to liberate a society you should give them free access to the Internet.
In the 1980s people would have thought something like Facebook would be an Orwellian nightmare since it collects so much data on people's habits and personal information. But people can say things on Twitter and Facebook or other sites that they cannot say or see in their real life. People in Muslim lands now have a portal to the world they never knew existed. And this is important in a lot of ways.
It is a double edged sword though. The Internet can show people in Muslim lands that their leaders are corrupt and their leaders use religion to oppress them. ExMuslims can form groups online that can help with the disorientation of leaving the religion.
The Internet can also be used for jihadist propaganda purposes. ISIS uses slick promotions to attract Muslims or others to convert to become Muslims in the Western world to join them. I don't know if he mentions it but their propaganda seems to be most effective to Muslims who do not have a lot of traditional Islamic teaching. So you have Muslims born in the West who buy into some really crap ideology. Who are you going to bomb?
ExMuslims and liberal Muslims are fighting for free speech, gender equality, LBGT rights, secularism and are willing to risk isolation, torture, and even death.
Then he talks about a quote from Thomas Friedman at 1:01 and says the number of exMuslims is on the rise and the war of ideas is ON!.
Then he addresses the audience in questions and answers.
I'll sum those up later.
