How Do You Defeat an Ideology When No One Fights

Somalia: Sheik Hussein Barre Rage in southern Somalia, who also serves as the chairman of the Islamic courts, has stated that in the town of Bulo Burto, you will be beheaded if you do not pray towards Mecca five times during the day. During prayer times, all shops are expected to be closed as well. If you are caught not praying, you "will definitely be beheaded according to Islamic law." "As Muslims we should practice Islam fully, not in part, and that is what our religion enjoins us to do." - Fox News
Wow. How do you defeat an ideology which leads to this type of law? Actions do speak louder than words, for words are useless in today's society. Say something about the Somali town and you are denounced as a racist or trying to impose your beliefs on someone else. Yes, it is so-o-o terrible that I believe killing someone for missing a prayer is too harsh. Shame on me. I should be reeducated to believe everything is totally relative, there is no good or bad, nor right or wrong. If you think that's the case, please go to this town and don't pray. Let's see you preach relativism to the local Sheik.
Will anyone stand up for what is right? Why is this radical Islam spreading so fast? (See first question) Look at the world from 600-900 A.D. Islam spread from Saudi Arabia all the way across northern Africa, even taking over Spain and parts of France in this short period of time. Then take 900-1300 A.D. Islam spread down the west coast of Africa and all the way through northern India (and it was not by peace. Notice the Hindu Kush Valley in India. It literally means "Kill Hindu" because thousands of Indians died on forced marches across the mountains to be sold as slaves in the Islamic markets.). Who would dare stand up to this? See the Crusades. And look at how they are demonized. Some have called it Europes first "imperialistic war." Just imagine a map in which the entire Middle East, West Asia, North Africa, Spain, parts of the Balkans and Greece were taken in just a few hundred years. Now imagine the areas of Spain and parts of curent Israeli coast taken and advances halted in the Balkans. Yes, it seems who was imperialistic.
Is that what we are afraid of? Will we be demonized in history for "imposing" our values on people? If the same liberal ideology is in charge, yes it appears we will be. But it is precisely becasue the liberal ideology is in charge now that we do nothing, nor say nothing. Hopefully history will know exactly where the blame should fall.
