Desi Muslims become radicalized when they are in USA.
In fact one of the reasons why they become radical is that they knew very little about Islam when they were in their home country. The countries where young men live a sheltered life even after they are married and have kids.
Thanks to this sheltered and over protected life, once they get to USA (or even West), they are lost for a mooring. And many cases such mooring is provided by local or internet based Jih@dist literature.
Desi Mulsims are raised with this $tupid idea of Pan-Islamism, and that pushes them even further into the hands of j@hil Islamists.
So obviously his poor parents are at loss to figure out what the heck went wrong with their innocent boy.
