They explore the unique mindsets of Muslim criminals in Denmark, an exploration of the violence prescribed in Islamic texts, immigration policies, and Islamic reform, among other topics.
He deals not so much to do with theology as with the cultural upbringing and psychology of many Muslims - though these things, as in all cultures, are based on one's religious worldview. In passing it is mentioned that the more educated a Muslim person is the more likely they may be to get involved in "extremism", violence or terrorism.
This is an hour long but delivers a clarifying perspective from an experienced health professional - and from a non-religious viewpoint. The interviewer also brings an useful perspective as a secular Jew raised in the Middle East.
The interview highlights the current emphasis in Western culture towards victim identity and the tendency to not take responsibility for one's own actions and future. Therefore there really is an uncomfortable dovetailing of Islamic background cultural emphases and Western cultural weaknesses which is unfolding before our eyes as nothing other than a capitulation - much of what we consider tolerance and being reasonable is interpreted as mere weakness by an incoming culture with very different priorities.
