Actually it's not that uncommon. The only problem is, those Muslims that hold to this ideal, do not read or study their own religion: and there are a lot of them. Therefore, to become "radicalized", all they have to do is start reading.
In Iraq - the Shi’ite - 70 or near 80 % of population, was illiterate.
They didn’t read or write - but had Clerics bent on Western destruction...they were “radicalized” to target US and Coalition Troops...
This moslem that acted decently - probably does not attend the mosque daily - does not hold grudges like traditional M.E. Arabs do - and cares nothing for the Arabic culture and traditions - so calling him a moslem is an error...
