I know, I started the thread, but you can't say everything he says is rubbish based on that.
Well that is rubbish and he stated it, so he does indeed talk rubbish. You can't go around changing the goalposts by adding an "everything" in.

If he would have said "Campbell was Blairs Minister for Propaganda" most people would probably agree.
But that would be rubbish too. Campbell was never a minister. Not to mention that Goebells was meant to be the architect of the Final Solution and while somewhat odious I don't seem to recall Campbell ever proposing genocide...
