If you look at his statistics he suddenly gained 200-300k subscribers in a few weeks.

He gained those when he made the Dubai video and it went viral because average westerner knows absolutely nothing about the rest of the world besides whatever advertisement travel agencies broadcast on their television.

And his Dubai video is genuinely good. It is comprehensive but concise. Goes straight to the root of the problems instead of beating around the bush. Unfortunately agreeing that Dubai is bad does not necessarily mean you are not a Nazi.
