This post is to do with a particular brand within Islam rather than Islam as a whole.
The classic dichotomy in certain Islamic thought was revealed by the poster in London during the Danish Cartoon Wars: "Behead all those that say Islam is violent." My initial reaction was to laugh out loud at the picture but on reflection it is sickeningly real.
Dialogue with this particular thought within Islam is impossible. Unreasoning minds can't grasp reason. Even a child can see the abscence of logic in the posters and placards but ideology isn't about logic. It's about self-perpetuation and growth, despite logic.
Sadly, this ideology will continue to grow as this branch of Muslim 'might' is seen to face-off and 'beat' the West. More arabic children will be taught nursery songs about eating the flesh of their enemies. More children will declare their intent on TV chat shows to become suicide bombers to claps and cries of 'Bravo' (sic) from the studio crew. More parents will mould their babies into the fuel to turn the world into a vast abattoir of paradox where law is unlawful, and right is wrong, and killing is good, and compassion is weak. I hope I'm wrong but history shows that a radicalised motivated minority will always defeat the decadent majority.
Where this leaves the lady in Sudan? Most of the protests are probably stage managed to put the heat on the UK government. To the Sudanese she's a pawn to demonstrate how weak the West is. One more victory to give to the radicalised sector of Islam. That's why they were so keen to get the radical imam in court, to associate the 'victory' with that sector within Islam.
