beyond that the guy seems to have an agenda ..... and where exactly does he get his information and how does he know that it's the truth?

Through this one must be using critical thinking skills and observing historical patterns. As well fundamental questions should always be asked such as, "Who benefits?" If that's an "agenda" I would suggest more adopt it.
