>It was not known what path Muhammad, a U.S. citizen who is a recent convert to Islam, had followed to radicalization.<
What path? One has to be a radical to “convert” to Islam in the first place. We the people, don’t learn anything when it comes to Islamic matters, do we?
I think most islamic fascists who were converted are either racists or they were converted into the cult the same as anyone else is converted into a cult.
