Is the rise of Extremist Islam the same as the Old Communism?

After reading this web article Somali Islamists seize checkpoints, demand sharia it seems that there is little difference between Islam's Sharia and Communism's approach to its people: extreme limitation to people's freedoms.

However, when you look at the other exteme of not giving citizens the right to protect themselves as it shows in Belgium in this aritcle “Youths” Kick Man to Death on Crowded Antwerp Bus it shows that governments that don't have the means to which to protect its citizens cause fear. But notice what the paper stated "Three Moroccans, two of whom are minors, were arrested today." While most Moroccans are muslims, these may not be following Islam or follow an extemist viewpoint.

What are the answers?
