It's obvious what his intentions are but we shouldn't blame him for thinking that way since Saudia is the strongest muslim country right now and since it currently represents Islam the same way Russia represents Communism, USA capitalism, Vatican Chritianity.
To the world Saudi Arabia = Islam.
It's one thing for some random dude to assume that the actions of Saudi Arabia equate Islam. It's something completely different when a former Muslim who grew up as a Muslim and personally knows many Muslims to believe that the actions of Saudi Arabia equate Islam.
He knows what he's doing here. He's being disingenuous for a reason.
