Kadame,
Once Mungiki got bored of beheading stubborn matatu crew, they turned on their own,fellow Okoyus. Central Kenians was terrorised and I think this was the tipping point. Michuki stepped in and he never disappointed. He mowed hundreds till he fell out with Kifacki.
I insist there is nothing like moderate Islam. This is a religion of violence. But soon or later they will turn on their own. You say Talibans executing Muslims in Pakistan. But they have so many non-Muslims to clear before they get to Muslims. Sad fact
