There are two things there. First of all let me shatter some misnomers. In the U.K. 47% of all the people who have been convicted for Islamist terrorism had a university education, and six of them were presidents of U.K. Islamic societies in the universities. Nearly 49% of the people who were convicted for Islamist terrorism in the U.K. had white-collar jobs and were integrated into society. So they had good jobs and a good education. That is not something that prevents people from becoming radicalized. There are always other grievances and other issues that radicalizers will use.
The other point's about thinking a certain way and de-radicalization. I would hope that any country that has a liberal, secular democracy would have a problem and want to de-radicalize people who, in an Islamic state or even in Canada or somewhere else, believe that anybody who changes their faith from Islam to something else should be killed. I would hope that they would actually try to do something about that either here or abroad. Also, anybody who believes that certain harm should be imposed on others should undergo some form of rehabilitation. I would hope and believe that these people would get the support they need, from an ideological perspective, to bring them back to some sort of normality.
