Just because something is too "out there" for you to believe doesn't make it automatically incorrect.....maybe you should question the information that formed the box you live in...instead of questioning those who are thinking outside of your box.
All i am saying is that when you are programmed for decades to believe only certain things are "real" and others are not i.e. reptilians....then of course Icke will sound wacky...but he only sounds wacky because of the constraints enforced upon our minds through mass conditioning.
