I think he believes what he is saying. This guy is a young Westerner who has converted to Islam. He is not a true Muslim, he is not representative of true Islam. He is a confused mind. He wants to see in Islam things that do not exist, things that are respectable. He is deluding himself.
But anyway, whether he is sincere or not, what difference does it make ? The bottomline is that the vast majority of Muslims either openly state that we should be destroyed or lie (taqiya). The bottomline is that Islam is rotten to the core and that our destruction is commanded by the Kuran and the Haddiths. The bottomline is that Muslims are our ennemies and that our determination to fight and win the war they have waged against us will not be influenced by lost and confused individuals such as this one.
