They are radical beliefs that are well supported and if you listened to it all you will have heard that these radicals support the extremist 99% in what they are trying to achieve ; a worldwide caliphate.
If you took the entire sharia law system and followed them in their entirety, sure, sharia is pretty radical. My issue is that Shapiro's depiction of the data is basically propaganda.
For example, one of the first statistics Shapiro states in his video is that according to a 2009 poll, almost 50% of the muslims in Indonesia support strict sharia law not just in Indonesia but in other countries. He then states that 70% of the muslims blame the US, israel or some other country for 9/11.
The same 2009 poll states:
Generally, supporters of sharia are most comfortable with its application in cases of family or property disputes. In most regions, fewer favor other specific aspects of sharia, such as cutting off the hands of thieves and executing people who convert from Islam to another faith."
Are muslims who mainly favor the application of Sharia law towards family or property disputes radicalised? Where is the mention of this in Shapiro's video?
In terms of the 70% of muslims who blame the US/Israel other country for 9/11, was the US completely blameless in what the Al-Qaeda thought were justified motives? Moreover are the people who think that the US aren't blameless actually radical muslims just for holding that opinion?
