I think the video has nothing to do with Muslims or with immigration. To me at least, it was apparent that he was talking geopolitics about Saudi Arabia.
For instance, with the money the royal family gets for oil, it creates mosques and charity organization that, while performing the social function they obviously would, spread a very strict version of Wahabi Islam. In many ways, this is why Saudi Arabia is the guardian of islam atm. They are spending as much money as they can to associate Islam with Wahabism, and have managed to spread the doctrine to the 4 corners of the world.
The point this guy made about European tolerance, wasn't that it was bad, or that Europeans placate too much, but rather that the Saudis understood how to manipulate it in order to set up their own propaganda stations for UK Muslims.
The Saudi's, through Pakistan's ISI, have funded the Afghan mujahadeen since the 80s, they support the Waziristan tribal groups against secular pakistan and afghanistan, they support the Taliban.
I honestly don't think concern over Saudi funded mosques, built on the premise of anti-muslim rhetoric, has anything to do with Muslims.
