Well I don’t like the term ‘Radical Islam’ either, because these terrorist represent ‘Orthodox Islam’.
There is nothing ‘radical’ about their terrorist activities at all. It is completely within the historical norms of Islamic orthodoxy.
The behavior of these terrorist is completely in adherence with the teachings of the Koran and the Hadeeths.
You beat me to it. It’s not “radical Islam,” it’s Islam, period. It’s what Muslims have always done, according to their most basic beliefs and rules.
