Apologists for Islam just do not seem to get it, do they. There is no such thing as "extreme/radical Islam" and "moderate Islam", there is just Islam. Some Muslims follow Islam as Mohammad dictated, and some don't. If Mohammad were alive today, he would be horrified, he would treat "moderate Muslims" with contempt and state that they are not Muslims. Anyway, no matter how much this truth is told, people choose not to believe it. Why? Because when you recognise there is a problem, you have to do something about it and it is just so much easier to remain blind, allowing one to opt out of doing anything.
Do you know what I want to live to see? I want to live to see progressives/liberals forced to live in a world that they have created. I want to see the looks on their faces when they finally understand what they have created. I want to see them realise that some of us conservatives were right all along and now it's too late to do anything about it. I want to see the horror on their faces when they know that their children and grand children will have to live in the world they have created because they were too damned ignorant, arrogant and condescending to those of us who can visualise the future that is coming and warned them about.
They don't want to see that not all cultures and religions are equal. They look at a video that you posted and will find some excuse, something that they can say that makes them think that there are Muslims who don't believe in what is stated in the Qu'ran and Hadith, who don't believe what Mohammad told them is the law. They can't believe that ordinary Muslims believe in EXACTLY the same things that those who are considered to be "extremists" and the only difference is, that in Muslims countries it's easy to live the live as a Muslim should, and a tad difficult to do so in non-Muslims countries (at the moment).
