I think the last 'Lord of the Rings' movie had it correct.
As we begin to bring the Ring that controls all Rings to Mordor we all turn slightly insane..its both the external and internal influences plus the kind of energy we can't fully deal with. Then again these are not ordinary times..
With that in mind you have to allow everyone to be a little nuts at times. I see Icke uses a plasma globe while talking, so he tries to be without 'influence' but that isn't always possible.
