text: The author was referring to young men in general, not young Muslim men only.  Nice try at setting up a straw man to easily blow down.  Most of the data the author quoted came from the USA, where Muslim young men make up an insignificant fraction of the overall population of young men.  Huge portions of urban USA have problems of violence, drug use, unemployment, you name it.  None of it is related in any way to Islam; in fact right wing Christianity has more influence in these areas.  Read the article again; the point is that young men in general throughout western society are growing up without the influence of a father figure and they end up easily radicalized as a result.  That means gangs in inner cities and peddling drugs, etc., and of course a small proportion also get involved in radical Islam.  Roughly half of the Canadian young men who joined ISIS, were not raised as Muslims and had absolutely no Muslim influence until finding ISIS on the internet.
