Radicalization is learned at home from loving parents, and  not simply from online video clips as you would have us think.  Radicalization is taught around the dinner table, eating mom's  home cooking,  as the adults  discuss  the destruction of Israel and evil Jews.   It is instilled into young minds with every nod of father's head at the mosque,  listening to fire-brand Imams preaching hell fire damnation of America  and the glory of martyrdom.   Radicalization is justified by how proud mom and dad are of  their son the martyr.
