In my book, "Mein Kampf" chapter six:
I give my analysis of the function of propaganda, I advise, "All propaganda must be popular and its intellectual level must be adjusted to the most limited intelligence among those it is addressed to.
Consequently, the greater the mass it is intended to reach, the lower its purely intellectual level will have to be, the art of propaganda lies in understanding the emotional ideas of the great masses!"
That's where Cameron is getting it wrong you see... he can't find, thus cannot communicate his propaganda lies at the greater masses level.
Just thought I'd give him some advice...
